sPHENIX MAPS tracker discussion

[Ming Liu <ming AT bnl.gov>]

Thank you Mandy for quick response,  so sPHENIX (INTT/TPC/MVTX) will be running again mostly during the night, is that the plan?  

Cheers,

Ming

Hi Ming,

No, there are still CMS groups. One of the CMS groups wasn’t able to come, but the other 2 are going to be here. They will be taking 120 GeV beam, probably 50 – 60k particles per spill.

 

Thanks,

Mandy

HI Itaru,

10kHz sounds like a good starting point.

 

Mandy - I heard no CMS/ATLAS next week, all sPHENIX, is it correct? In this case, we may be able to run parasitically during the days also.

 

Cheers,

Ming

Hi Ming,

 I read back e-log record from the last year's beam test. I think we would like to start with ~10kHz beam and gradually increase as long as data look healthy.

Best regards,

Hi Itaru, Tom and all,

Sure, understood. Last time it took CAD ~0.5hr to switch to e- beam.  I guess INTT could also use the e-beam to scan the material budget of the detectors.

 

Also for the nominal runs, at what intensity would you like to run to proton beam, ~15kHz? ( ~60K protons per spill).

 

Cheers,

Ming

Hi Ming,

 It is OK for us to run with 5GeV e-beam for a few hours.

Hi all, cc’d Mandy and Evan,

 

As of today, we are pretty much ready for sPHENIX MVTX 2^nd test beam run next week.

1. Telescope system was set up in MT6.2C, and passed ORC and tested on Monday. Nice work done by Cameron, Gerd and Fermilab techs!
2. Sho fixed some minor leaking issues of the cooling system today, thank you Sho!  
3. A new readout mode is developed to use 4-stave telescope to study tracking/hit efficiency vs strobe delay, good work by Sho, Alex et al.
4. At LANL, we have successfully integrated external laser and MOSAIC test bench and taken initial MAPS parameter scan runs with adjustable trigger delays. More scans for MAPS operational optimization will continue for next a few days.  Zongze has developed multiparameter scanning code to simplify the operation, nice work!
5. Our current plan is to start data taking from the evening of 6/19 to the end of the run. The goal is to crosscheck laser scan results (optimized MAPS parameter sets) with test beam data (laser beam tuned ~ MIP, but needs confirmation).
6. If OK with INTT and TPC run plan, we would like to take more 5GeV e-beam data for MVTX stave material budget scan near the end of the run (~ a few hours should be good).  

 

Cheers,

Ming
