sPHENIX MAPS tracker discussion

[Xin Dong <xdong AT lbl.gov>]

Hi Joe and HaoRen,

Thanks a lot. The runs after 47002 contain the MVTX cluster phi distributions. The summary of the run dependence can be found below.

I see there are more runs appearing in the directory. I can keep updating the figure with more data coming in.

Thanks and Best Regards

Hao-Ren is correct. Those files are being aggregated, they are much larger so they take longer to aggregate. But they show up in the same directory under *CLUSTER* instead of *SEED*.

Hi Xin, all,

I think the MVTX cluster QA module is already merged into the coresoftware: https://github.com/sPHENIX-Collaboration/coresoftware/blob/master/offline/QA/Tracking/MvtxClusterQA.cc

Newer runs should have the cluster histograms from the production.

Best,

Hao-Ren

Hi Joe,

Thanks. I took a look at several root files. It seems the MVTX cluster QA histograms (cluster vs. phi particularly, not associated with tracking, just all clusters) are not saved in these files. Probably we should encourage Hao-Ren to integrate his code updates into the production so we can monitor them along with the run goes.

Thanks and Best Regards

You can find many runs produced as a part of the production here:

/sphenix/data/data02/sphnxpro/QAhtml/aggregated/*SEED*

Take a look and let me know if you find issues,

Joe

Hi Ming and All,

I looped through all the runs that Hao-Ren generated (actually turns out only 7 runs have the valid entries). Please see the updated slides in the same indico location

https://indico.bnl.gov/event/24069/contributions/93529/attachments/55585/95138/20240701_MVTX_BeamLine.pdf

The run dependence can be found here. It is reasonably stable up to 46677.

Hi Haoren, if you have new production data, feel free to share. 

I also put the macros and figures in the following Git directory.

https://github.com/starsdong/MVTX/tree/main/2024/BeamLine

Comments are very welcome. Thanks and Regards

Hi Xin and Hao-Ren,

 

Nice! 

Yes, I agree we should have the beam centered wrt to MVTX for best physics, and we  

 

Hao-Ren, did you use the ideal geometry or the updated one from Yasser’s corrections?  

 

Cheers,

Hi All,

 

Thanks Hao-Ren for generating the QA histograms. Based on his root file, I did a quick analysis and please see the findings below

 

https://indico.bnl.gov/event/24069/contributions/93529/attachments/55585/95095/20240701_MVTX_BeamLine.pdf

The slides are also posted to today's MVTX meeting indico page

 

The proposed actions can be found in the last page:

 

1) W.r.t. the condition for the data that Hao-Ren generated, I would propose we request CAD to move the beam orbit at sPHENIX IR horizontally towards x+ direction by 4mm, and if possible, also vertically downwards by 1mm.

 

2) But, the beam position may change, particularly considering recent changes in terms of beam conditions, we should re-analyze the latest beam data and check again.

 

3) We should continue monitoring the beam position throughout the Run. The MVTX cluster phi distributions are a good measure to monitor this.

 

Comments and suggestions are more than welcome. Thanks and best Regards

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
