A talk on the iTPC was given to the instrumentation group on December 03 by FV. The talks is attached to this page.
September 2016 iTPC NP review
The review was held on September 13 & 14 in Washington DC
All the talks and background material is available at the BNL indico page
The closeout report will be posted once finalized.
I already extracted the recommendation and the comments that needs some action. Note it is preliminary since we do
not have the final report, but it should still beuseful. See attachment. (9/20/16)
The final close-out report was received on 12/14/2016 nd attached to this page. See list below

The talks from the Jan 2016 Directors review are on the BNL indico page
Response to recommendations
Update on KPP -- we asked for more time on this which was granted
We are suggesting a path forward for adding a KPP that reflects that the UPP dE/dx is achievable. At the review it was suggested, for example, to use the width from using signal from an 55Fe source.
The connection between observed resolution of an 55Fe source and final dE/dx is not trivial. The resolution of the source does e.g. depend on how the signal is read out e.g. via the pads or the wires.
We are pursuing this by simulations of MWPC response to 5.9 KeV electrons, by reviewing historical records since part of the original acceptance criteria was a scan of all sectors with sources, and investigating the just started tests with 55Fe source and X-ray gun at SDU, all to understand what the ideal response to stand alone measurements would be.
We hope you will agree to such a path forward and the plan is to aim for having a quantified proposal by January 30 2017 for this KPP. Enclosed are the suggested table, and text.
The first response was by Oct 15 to provide an updated KPP. The repsonse that was send in is attached here
By November 1 we have to provide a workforce plans
The iTPC group should work with RHIC management to anticipate and identify workforce needs for construction, installation, and commissioning and develop a plan to mitigate any schedule risk due to a lack of technical and mechanical support personnel. Submit the workforce plan to DOE by November 1, 2016.
I have worked with a few members of iTPC and STSG to come up with the first estimates. These are contained in two documanents
one describing the activities, and a second with a summary of resources. Its not yet complete.
See the attached documents.
The second items is
Generate a Lessons Learned document from the construction and commissioning of the original STAR TPC and submit to DOE by November 1, 2016.
This has been discussed and Jim proposes to generated a document with the many-many presenteation that we have assembled, and write an introductionary
document. This may actually serve us well to assemble all this material in a coherent fashion.
Document was submitted on time
The testing plan was submitted to DOE in mid September 2017 ahead of the yearly review.
iTC Risk assesment

iTPC meetings
A child page maintains a list of all tpc meetings and the technical meetings held
for integration , installation. Some presentation are listed on that page
The meeting summary up to October 2015
was kept in Quingha's blog page here
The mechanical meeting series is complete with the final installation of all sectors on October 2018
Bi (or weekly) weekly meetings of internal iTPC working group to define, and follow up on mechanics, and installation. Currently on Mondays at 1.00 pm.Meet in 1006 using the STAR ops standing eZuce reservation. Minutes attached (latest update 7/7/2016) from earlier meeting. The individual meetings will show up in list below here from. Meeting is led by Robert Pak, with engineers, techs, physicist and from BNL and LBL, and minutes written by him.
