BES Milestones


Dear RHIC Spokespersons:
I am writing again to update my request for the beam use requests for the coming RHIC runs.
In consultation with the Office of Nuclear Physics we have decided to make a change to the future RHIC run schedule. Specifically, we now plan to run RHIC in both FY16 and FY17, followed by one year (FY18) without a RHIC run during which the low energy RHIC electron cooling (LEReC) system will be installed. The high statistics Beam Energy Scan II is then planned for the years FY19 and FY20. The modified plan will allow for a less aggressive schedule of the LEReC project. It will also relax the conflict between the heavy ion and spin physics programs of RHIC that remained unresolved at last year’s PAC meeting.
I request that you submit the annual beam use requests by May 19, 2015. The BURs should be for a 22-week RHIC run in FY16, and either a 15-week or a 22-week RHIC run in FY17.
I also ask the STAR Collaboration to present the iTPC proposal to the PAC and to provide an update on experimental efforts aimed at exploring possible phenomenological manifestations of the chiral magnetic effect.
Both collaborations should present a tentative schedule for the release of results from the data taken in runs 13 and 14 (p+p, Au+Au 15, Au+Au 200, 3He+Au).
Thanks, Berndt

Subject: performance milestones
Dear RHIC Collaboration spokespersons & Frithjof:
I received a "heads up" from Jim Sowinski that a main scientific performance milestone for nuclear physics in FY15 will be the completion of the analysis of the 15 GeV Au+Au data from Run 14 and the connection of the BES data with lattice QCD calculations. Here is the statement in more detail (Jim's words in blue):
“FY15:  Measure bulk properties, particle spectra, correlations and fluctuations in gold + gold collisions at Relativistic Heavy Ion Collider (RHIC) to search for evidence of a critical point in the Quantum Chromodynamics (QCD) matter phase diagram.”
We recognize that significant progress has been made in finalizing and collecting the results from Beam Energy Scan I to make the case for BES II.   In evaluating this goal we will primarily be looking at producing results from the 15 GeV run carried out last year.   Other efforts that might contribute towards this measure could be results from the fixed target data taken last year and theoretical efforts such as progress towards better connecting measurements to QGP properties or extending LQCD calculations toward finite chemical potential.
It will be important to have tangible results to point to by the end of September 2015. To me this looks eminently doable and desirable in view of the Quark Matter 2015 conference in Kobe.
Let me know if you have any questions.

2001 original bylaws

Revised Sections II and III 28 November 2001


I. Collaboration Membership

  1. Members

    Scientists, graduate students, engineers and other technically-oriented persons intending to make a significant contribution to this collaboration over a period of a least one year are eligible to be members. Members of other RHIC collaborations will not be members of this collaboration without permission from the Council.


  2. Institutions

    Institutions (universities or laboratories) are admitted to the Collaboration by the Council upon recommendation of the Spokesperson. Normally an institution will have at least two Ph.D.s who are eligible to be members. Each institution is responsible for its list of members and for designating a contact person who will receive and disseminate collaboration information within that institution.


II. Council

  1. Membership

    The Council will consist of one member from each collaborating institution who will represent the membership from that institution. Institutions are admitted to the Collaboration by the Council upon recommendation of the Spokesperson and upon receiving an affirmative vote of at least 75% of the Council. Each institution will select its representative. Institutions may also be admitted to the Collaboration without Council membership. Such an institution should be affiliated with another institution which has Council membership and may be given its own Council membership at a later time by a vote of the Council. The Spokesperson and Deputy Spokespersons will be ex-officio members of the Council. The Council may add extra members.

    Younger members of the collaboration will be represented by up to three at-large Council members with no more than five years experience beyond the Ph.D., at least one of whom should be a graduate student. Candidates for at-large positions can be either self-nominated or nominated by others after a call for nominations by the Spokesperson. The at-large representatives will be elected by those members of the collaboration with no more than five years experience beyond the Ph.D. Elections should take place at least every two years.


  2. Function

    The Council will deal with general issues which concern the collaboration. Examples include the organization and governance of the Collaboration, adoption of the bylaws and amendments thereto, the policy on admission of new members and institutions to the Collaboration, and publication policy. In addition, the Council is responsible for election of the Spokesperson and for approval of Deputy Spokesperson appointments.


  3. Governance and Meetings

    The chairperson of the Council is elected by majority vote of the Council from among its ranks. The term of office is two years, and is not renewable. At the end of the Chairperson's first year in office, a deputy is elected who will become the chairperson's successor. After the end of the chairperson's term of office, the chairperson will serve yet another year as deputy.

    Normally, Council meetings will be held during collaboration meetings. At the discretion of the Council Chair, additional meetings can be called with at least two weeks notice. Any Council member unable to attend a given meeting can name a substitute representing the same institution or group. All Council meetings will include a closed session, without the Spokesperson and Deputy Spokesperson(s) present. Elections by the Council, of the Spokesperson or Council Chair or Deputy Chair, must be announced publicly to the entire collaboration at least two weeks in advance of the meeting at which the elections will take place.


  4. Voting

    The Council will make decisions on all issues except elections and admission of new institutions based on a simple majority of all voting members. Any member may call for a secret ballot. Votes on adding extra members, admitting new institutions, or amending these bylaws must be announced ahead of time. Proxies to the Council chairperson are allowed for non-election votes, as are electronic meetings and ballots.

    Voting for Spokesperson will be carried out by secret ballot, and without proxies, at publicly announced Council meetings. A quorum of 60% of Council members must be represented at the meeting for a valid vote. A candidate for Spokesperson can be elected in the first round of voting only if he or she receives more than 50% of all votes cast, including abstentions. If no candidate obtains this absolute majority, runoff rounds will be conducted for the top vote-getters until one candidate obtains more than 50% of the votes cast, not counting abstentions. The re-election of a sitting Spokesperson requires a 2/3 majority of the voting representatives present at the meeting.

    Candidates for Spokesperson can be nominated by any member of the collaboration. An ad hoc nomination committee consisting of the Council Chair and two Council members appointed by the Chair will solicit nominations at least 30 days before the election, and will prepare and oversee the ballots.


III. Spokesperson

  1. Selection

    The Spokesperson is elected by the Council and serves at its discretion. The normal term of office is 3 years, renewable with a 2/3 majority of the voting Council representatives present at the meeting.

    The Council can decide to terminate the Spokesperson's term in office at any time and to request new elections. Such a termination requires a 3/4 vote of the representatives present at a Council meeting with a quorum of at least 2/3 of the members represented.


  2. Function of the Spokesperson

    The Spokesperson will be the representative of the Collaboration in scientific, technical, and managerial concerns. The Spokesperson will be concerned not only with the design and construction of the detector and its upgrades, but also with all other preparations required to operate the experiment efficiently and to publish results in a timely and responsible fashion, and with continued leadership of the Collaboration.


  3. Deputy Spokespersons

    There will be up to two deputy spokespersons. The spokesperson and the deputies must all belong to different institutions. The deputy spokespersons will be appointed by the Spokesperson subject to the approval of the Council. The deputy spokespersons provide support and assistance to the Spokesperson in the management of the experiment and collaboration. They may be appointed by the Spokesperson to act on his or her behalf and to represent the Collaboration.


IV. Adoption

These bylaws were adopted by the Council on 21 June 1991 and amended on 16 Nov. 1991, 21 April 1993, 7 Nov. 1995, and 28 Nov. 2001.

Goals. The publication goals of the STAR Collaboration are as follows:

  1. The speedy publication of results that the Collaboration has agreed are sound and ready for publication. Here "publication" means the announcement of results through seminars, conferences, and/or scientific journals.
  2. The avoidance of rumors and premature publication. 
  3. The equitable assignment of credit to individuals for their work.



The following policies and practices have been adopted to further the above listed goals:


  1. Data from all parts of the STAR detector shall be available to all members of the STAR Collaboration for analysis. Furthermore, it is the responsibility of all collaborators to see that the necessary correction algorithms and correction parameters be updated and made available to the entire Collaboration in a timely manner. Any member of the Collaboration is free to analyze any part of the data.
  2. Given the overriding principle of open communication within the collaboration, collaborators should, upon request of a colleague, provide relevant code and input assumptions that would permit results to be checked and confirmed.
  3. Members of the Collaboration should exercise caution and good judgment when discussing experimental results with individuals outside the Collaboration before the results have been published (i.e., presented publicly in a seminar or conference or submitted for publication in a scientific journal). These results should clearly be labeled "Preliminary". When individuals outside the Collaboration are consulted for advice on the analysis or interpretation of the data, those individuals should be asked to respect the confidentiality of the data.
  4. Members of the Collaboration should not present unpublished experimental results in seminars or conferences until (a) a memo has been circulated to the Collaboration giving details of the analysis and results, and (b) a rehearsal has been held in front of several members of the Collaboration, including a Council member and, if possible, the Spokesperson. In particular circumstances the Spokesperson may waive both these requirements.

    The Spokesperson will be designated as the Talks Coordinator. He will strive to distribute speaking invitations received by the Collaboration on the basis of the suitability of the speaker to the topic and an equitable distribution of talks to individuals and institutions with appropriate consideration of regional distinctions. As an aid to this end, he will maintain a record of all talks; thus members of the Collaboration who receive personal invitations to give talks should inform the Talks Coordinator. Speakers are encouraged to deposit a copy of their transparencies in a file which will be maintained by one of the secretaries.

  5. A paper should not be submitted to a scientific journal until the above requirements have been met and (c) a not-far-from-final draft of the paper has been discussed at a general meeting, and (d) the final draft has been circulated. After the discussion of the not-far-from-final draft, an ad hoc committee may be appointed by the Spokesperson to facilitate the preparation and submission of the final draft. This committee would consist of the principal authors and one or more individuals not directly working on the analysis. It would be empowered to adjudicate disagreements on details of the paper. In addition, the Spokesperson will maintain the list of publications.
  6. The Spokesperson will maintain the Collaboration's current author list. In general, the authors of papers will be those collaborators who have contributed to the taking or analysis of the data reported in the paper. In recognition of their contributions, collaborators who have worked on the installation of new equipment but have left the Collaboration prior to the taking of data will be included on the initial papers of the Collaboration using that equipment. Normally individuals are dropped from the general author list one year after they leave the Collaboration; however, individuals who have made special contributions to a given topic, either in hardware or analysis, should be retained on the author list of papers for which their contributions are relevant. Technical papers need only list as authors those individuals who contributed to that project, but the "STAR Collaboration" should be acknowledged. Decisions on the inclusion of authors will be done on the basis of these guidelines by the Council member from the author's institution with the concurrence of the Spokesperson.

    The authors of papers will be listed in alphabetical order, preceded or followed by the phrase "STAR Collaboration". Papers which result from student's theses should be so indicated by appropriate footnotes. Papers for conference proceedings are normally submitted in the speaker's name, plus other major contributors if appropriate, plus "STAR Collaboration", and require only the Spokesperson's agreement on the wording of the text.

  7. The Spokesperson will maintain a list of students' thesis topics which will be updated at collaboration meetings. The Council may aid in resolving any conflicts.
  8. Members of the Collaboration should not issue press releases or call press conferences without the approval of the Spokesperson, who will consult with the members of the Council.

The Charge:



A call for the annual Beam Use Request (BUR) has been sent from the BNL ALD to RHIC collaborations on February 22nd, 2017:

Dear RHIC Spokespersons:

I am writing to request that you submit the annual Beam Use Request for the RHIC runs in 2018 and 2019 and related material.

We current[ly] anticipate, assuming favorable budget conditions, runs of 15 cryo-weeks (including 2 weeks for the Coherent electron Cooling test)

in FY2018 and 24 cryo-weeks each in FY2019 and FY2020. Less favorable,

but still likely, budget conditions would only allow for a combined run of 20 cryo-weeks in FY2019/FY2020. The beam use request should consider both possibilities.

The submissions are due by May 15, 2017. Since PHENIX has ended data taking and sPHENIX has not yet started construction, I expect to receive a BUR from STAR only.

I also ask STAR and PHENIX to report on the status of analyses of data from previous RHIC runs, especially the runs in 2014-16.

In addition, I invite the STAR and sPHENIX Collaborations to present letters of intent for proposals of modest forward upgrades to their detectors for data taking after 2021 for consideration by the PAC.

The dates for this year’s RHIC PAC meeting are June 15-16, 2017. A list of current PAC members is attached for your information.

Thanks in advance,

Dear Helen & Zhangbu:

I am writing to solicit the STAR beam use requestDear Helen & Zhangbu:
I am writing to solicit the STAR beam use request for RHIC Run-19
and to request presentations from the RHIC collaborations at this
year’s PAC meeting, which is scheduled to be held on June 7-8, 2018.
We anticipate the 2019 RHIC run to constitute the first year of a
two-year high statistics beam energy scan. The 2017 PAC assigned
highest priority to proposed Au+Au runs at 11.5, 14.5, and 19.6 GeV, 
interleaved by brief fixed target runs at the same beam energies, as 
well as dedicated fixed target runs corresponding to CM energies of 
7.7, 6.2, and 5.2 GeV. The PAC tentatively recommended Au+Au runs in 
the collider mode at 9.1 and 7.7 GeV during the 2020 RHIC campaign.
The STAR collaboration should not simply take these tentative 
recommendations as a given, but reconsider and justify the prioritized 
set of beam energies and the requested accumulated statistics at each 
energy, assuming either 24 cryo-week runs or 20 cryo-week runs in each 
of the years 2019 and 2020.
The beam use request should be submitted no later than May 1 in order 
to allow the PAC members to study it in detail before the meeting.
In addition to the STAR beam use request, I would like to request
updates from STAR and PHENIX on the status of results from Runs 14-17 
(14-16 for PHENIX).
Best regards

Official charge Berndt Mueller

Dear Helen & Zhangbu:
I am writing to solicit the STAR beam use request for RHIC Run-20
and to request presentations at this year’s PAC meeting, which is 
scheduled to be held on June 10-11, 2019.
The 2020 RHIC run will be the second year of the planned three-year
high statistics beam energy scan. The 2018 PAC tentatively assigned 
first priority for Runs 20-21 to data taking in the collider mode at 
7.7, 9.1, and 11.5 GeV CM energy, accumulating at least 100M, 160M,
and 230M min bias events, respectively. Second priority was assigned
to fixed target runs at 3.0, 3.2, 3.5, 5.2, and 6.2 GeV CM energy, 
acquiring at least 100M events at each energy, but did not specify 
exactly in which order these data should be taken, except that 
optimal use should be made of the availability of electron cooling 
to enhance the luminosity.
The STAR collaboration should not simply take these tentative 
recommendations as a given, but reconsider and justify the 
prioritized set of beam energies and the requested accumulated 
statistics at each energy, assuming either a 24 or a 28 cryo-week 
run in FY2020, followed by a 20 cryo-week run in FY2021. STAR should
also consult with C-AD about the number of dedicated LEReC 
commissioning weeks that are expected to be required during Run-20.
In addition, I request presentations on (i) the status of data 
analysis from previous RHIC runs and (ii) an update of the physics
goals for a short (16 cryo-weeks) forward Spin physics run in FY22 
with 500 GeV p+p collisions. 
The beam use request should be submitted no later than May 15 in 
order to allow the PAC members to study it in detail before the meeting.

Electronics Lab private network


Plan Overview:

In Room 1-232 (the "Electronics Lab"), our goal is to remove experimental test equipment and unsupported (or poorly supported) computer systems from the "public" network.   These are likely sources of Cyber Security concerns and may benefit from a less volatile network environment than the campus network.  To do this, we will create a private network in the Electronics Lab, with one maintained Linux node that will be dual-homed on the public network to act as a gateway to access the private network as needed.   With the introduction of one (or more) Linux box(es), eventually we hope to retire the old Sun workstation completely.

The address space we will use is (256 IP addresses).  This is "registered" with ITD network operations as a STAR private network, so that if anything "escapes" from the private space into the campus network, they will know who to call.

Given the short list of anticipated devices (below), no name server is planned, nor other common network services such as DHCP (subject to change as needed). 

Devices Using This Network:

  1. The Linux gateway system -- (Scientific Linux 4.5) using
  2. One Sun Ultra E450 -- "svtbmonitor" (Solaris 8) using 
  3. One serial console server using 
  4. Several (~4-5) rack-mounted MVME or similar devices at any time.  An initial set have been assigned  A set of working sample boot parameters are included in a file attached to this page (see the links in the Attachments section below).
  5. Update August 4, 2009:  Six more processors are being added to the network.  The name trgfe6 through trgfe11 have been assigned (ie. added to /etc/hosts on presley and svtbmonitor).
  6. Several Windows PC's, including laptops that may come and go (which will require manual configuration -- a small inconvenience that can perhaps be overcome with networking "profile" software that stores multiple configurations on the node -- to be investigated, such as


A Linux box named is configured on the public network, with a second NIC using to act as a manual gateway node as needed.  It is in the south-west corner of the lab.  An account named daqlab has been created (contact Wayne or Danny for the password if appropriate)


For the effort to replace svtbmonitor,  the home directory of svtbmonitor's testlab account have been copied over to presley in /home/svtbmonitor/testlab. 

Danny and Phil identified a handful of files from svtbmonitor as important so far:

  • emc.tcl
  • smd_qa.tcl
  • tower_qaodt.tcl
  • grab (compiled C code to open a window and connect to a specified node on the serial console server)
  • grab.bag (used by grab to "resolve" common names into ports on the console server)

The original versions of these files are all in their original (relative) paths, and modified versions for presley and the current networking setup were created and put in /home/daqlab/.  The Tcl scripts were modified to account for the slightly different environment on presley and were demonstrated to work (at least the basics - still needs testing to confirm full functionality).  The "grab" executable had to be recompiled from source (simple enough - the required source code consists of "grab.c" and only required a single minor change for the new environment on presley).  So far so good there.


Two small "desktop" 10/100 Mbps switches have been connected to each other to serve as the "backbone":

  • one is on a shelf on the west wall
  • the other is on a shelf on the north wall


This is easy to expand with one or two 16-port switches if needed (well, it actually is needed as I write this...).  (In fact, these switches have been rather fluid in the first months, coming and going and being swapped for others, all at a slight inconvenience to those of us trying to work with them...)

[Feb. 19, 2009 update -- the physical layout of switches and cables has been switched around many times since this description and I don't know the current state.]

The old networking (not to mention the serial lines) is a mess of cables, old hubs and switches that I plan to ignore as long as possible, though most should be removed if it isn't nailed down.  [Feb. 19, 2009 - some clean up appears to have been done by the folks working in the lab.]


To Be Done, moving from svtbmonitor to presley (last updated, Feb 19, 2009):

Towards this end we've identified the following remaining tasks:

Configure backups of the home directories on presley as another safety net for the critical content from svtbmonitor that has been transferred over.

Jack Engelage and Hank Crawford have transferred a bunch of files from svtbmonitor to presley [are they done?].  A "trigger" group was created containing Jack, Chris and Hank.  They have /home/trigger to share amongst themselves.

The biggies: 

VxWorks compilers for Linux and booting the VME processors from presley.  [Feb 19, 2009 update:  Yury Gorbunov (and Jack Engelage?) have made successful boots of trgfe3 from presley via FTP, so it looks like svtbmonitor has a chance of being retired at some point.  Sample boot parameters are attached]

Web master

The STAR www site is divided into a few parts, most will converge to a unique Drupal based content management system as time will unfold.

As a Collaboration, STAR makes use of the web for much of its daily functioning: communication, documentation, organization and many other activities. In addition to being a tool for the Collaboration, the web also serves as a means for introducing our experiment, sharing our enthusiasm, and conveying our results to the rest of the interested world. This includes both scientists and non-scientists alike.

For more information about this www site, contact the appropriate person below.
