sPHENIX tracking discussion

["Huang, Jin" <jhuang AT bnl.gov>]

Hi Everyone

As just discussed in shift change meeting, we will have a special TPC meeting at  Tue July 30 9:30AM tomorrow. Indico and zoom at https://indico.bnl.gov/event/24338/ 

TPC HV is being ramped for the first time after the new Isobutane gas mixture was circulated since Sat. We aim to collect sufficient cosmic data to establish the new GEM gain and a MIP-efficient HV work point priory to operate with collisions in the next steps. 

• Detailed plan are https://docs.google.com/presentation/d/e/2PACX-1vTvzKNq1u7-TICoJrPTI_wF9h-fa18lqR5c_Iqic3kKSp-eU5tfohVNuCYMfKwxTFoVihQngkbMELF6/pub?start=false&loop=false&delayms=3000 
• Live action at https://chat.sdcc.bnl.gov/sphenix/channels/tpc-electronics 

There could be many changes of the plan depending on factors like the detector response, and power stability etc. So, please stay tuned. 

Cheers

Jin
