APS talk
Here are pdf and pptx files of my talk for the South Eastern APS conference on November 15.
pixel geometry for misalignment work
Possible Causes of Data/Theory Discrepancy
HF Meeting 12.11.06
Wei suggested to:
- use the narrow values values around the mean obtained form Bischel function (Mustafa will send me the data)
- try my code on Yifei's muDSTs to to validate it
ppv test w/ and w/o BTOF with run12 real data (three trigger rate levels and serveral triggers)
Done with help of Xin Dong and Frank Geurts.
Xin's original study can be found at http://drupal.star.bnl.gov/STAR/subsys/tof/ppv-with-use-btof
Xin found that the TOF status table is not up-to-date, and suggested this could be solved somehow by hard code in StiPPVertex(Done).
Three runs at different luminosity levels are selected in this test. Data samples are selected large enough, as to statistical errors are quite small.
Production chain optoins(http://www.star.bnl.gov/devcgi/dbProdOptionRetrv.pl) are
pp2012a,mtdDat,btof,fmsDat,VFPPVnoCTB,beamline,BEmcChkStat,Corr4,OSpaceZ2,OGridLeak3D,-hitfilt
The test of ppv w/o tof was done at STAR_LEVEL=SL12d, but, for ppv w/ tof, it was done at STAR_LEVEL=SL12b.
Definition:
good Vz : vertex with positive ranking
PPV efficiency = (events with good Vz & |Vz-VpdVz|<6cm) / (total)
PPV efficiency2 = (events with good Vz) / (total)
By "total", it means all events marked by certain trigger.
| Luminosity | runnumber | trigger rate | #events | #events(test sample) |
| High | 13069013 | 14407.40 | 3M | ~0.78M |
| Medium | 13069023 | 9314.20 | 3.3M | ~1M |
| Low | 13068037 | 6280.70 | 2.76M | ~1.3M |

The (so far) agenda for the meeting today includes:
1) I posted an updated version of my UCLA-HF talk about HFT goals for Run-13.
It includes some hard numbers after Flemming/Amilkar produced/found some
important plots. Have a look and make comments if any.
2) I gave a summary of activities and plans in the HFT meeting (face to face). The talk is here:
http://drupal.star.bnl.gov/STAR/event/2012/12/04/hft-management-and-technical-meeting/software-prep-eng-run
It contains slides about recent Alignment work. Time permitting I will prepare some more for today's meeting.
3) In the same meeting Hao presented a Survey update. The file is here:
http://drupal.star.bnl.gov/STAR/event/2012/12/04/hft-management-and-technical-meeting/pxl-survey
4) After an impasse in resolving the dZvsz 'kink' bug in Alignment we talked to Yuri and he suggested
a few things. Half of the effect is gone now and we are confident that we will close this bug after we
get some TFS (Tpc fast simulator) irregularities fixed. Jonathan is preparing a few slides on this topic.

a) The long persisting bug of Z-split in alignment is resolved. Some minor issues are remaining at ~10micron level plus usage of TRS in simulations. Jonathan has a couple of slides on this.
b) As we get closer to the engineering run, and run-14 next year, Jerome asked me (again) to migrate codes and modules we use into the official dev, CVS controlled areas since we need to follow standard admission and QA procedures. This means that code in private dungeons, twisted this or the other way to work, or code in concept form etc needs to get materialized, selected, streamlined, tested, reviewed and become part of the STAR library. To this end I will have as a standard item in every meeting progress on this item. The agreement is to start with the simulation codes but we also need to develop the data stream as well, especially for the PXL part. Jon. and I will start building an outline of what is needed, a seed diagram to start the discussion as we first need to clarify/identify the modules we need, the sequence of implementation and the ordering of the compromises we make as intermediate steps are needed.
c) Yaping put together some excellent documentation of his work on IST modeling. This should serve as an example to follow. I haven't seen something so thorough since the days of Liliian Martin's docs in the SSD area. Yaping's work on the IST slow simulation and Geant modeling are two examples of pieces of work we need to implement and start using in our simulations.
d) Jerome is looking for volunteers to help evaluating the STV tracker. This is the evolution of STI, our standard tracker in STAR, but with many features and add ons, like working inside root-VMC etc etc. Jason put some initial info (links) here:
http://drupal.star.bnl.gov/STAR/blog/jwebb/2012/dec/10/stv-base-qa-code-archeology
Our group committed some help but let me know if you are interested. This is a thankless, service job but an excellent opportunity for students to jumpstart work in STAR computing environment.
