sPHENIX MAPS tracker discussion

[Xin Dong <xdong AT lbl.gov>]

Hi Hao-Ren,

Thank you. I have one question regarding the MVTX cluster phi distribution. You labeled "w.r.t origin". So what origin was used here for the cluster phi angle calculation? If you can clarify, that would be much appreciated.

Thanks and Best Regards

Hi Xin,

I just uploaded my slide to the indico page: https://indico.bnl.gov/event/24069/contributions/93529/attachments/55585/95090/MVTXComm-20240701.pdf.

You can find one of the histogram files under my working directory: /sphenix/user/hjheng/sPHENIXRepo/macros/TrackingProduction/HIST_PHYSICS_run2pp_new_2024p001-00046667-0000.root

(You may find the histograms in this file are not the same as the plots I showed in the meeting. I figure a run without any stave missing is more convenient for you to make use of it.)

Please let me know if you have any further suggestion to the QA module.

Best,

Hao-Ren

Hi Hao-Ren,

Could you post your nice QA slides you showed today at the MVTX meeting to indico? Particularly, if you can also share with me the histogram root files for the MVTX layer cluster density distributions vs. phi and the event Vy vs. Vx, I can try to do a quick calculation on the beam position shift w.r.t to the MVTX center and we may feed back to the operation team and make the request.

Thanks and Regards
