Commissioning and running of sPHENIX

["Park, JaeBeom" <jpark4 AT bnl.gov>]

Dear all,

Please find the outcome / HW from today’s BCO meeting. 

We will resume the meeting tomorrow after the SCM. 

For those who presented their materials, please upload your slides into the indico.

Outcome & HW

1. INTT timing offset calibration

• INTT experts (Jaein, Joseph etc.) will start working on automated pre-pass offset calibration in triggered mode
• INTT experts (Genki etc.) will study and show the verification on the offset in streaming mode 

1. INTT pool update : Martin will verify the updates with more runs and work with Sam to deploy in the main software
2. INTT streaming readout data integrity 

• Sam found phases of INTT streaming readout data similar to Takashi’s finding
• Could be handled in the event combiner — no changes needed
• In parallel, Raul will try to make a fix with manipulating the time of flashing data

Parallel event combiner

• Very good progress in parallel running per readout unit — much faster than before
• Inconsistent result in INTT BCO matching — needs to be investigated
• Need to rewrite the functionality to calculate the “all” FEE matching

Next meeting

Date : Thursday, Aug 15th after the SCM (around 16:30 PM ET)

Dear all, 

We will resume the tracking subsystems BCO alignment meeting tomorrow after the shift change meeting.

As there are a lot of things to be addressed, we will try to focus on shorter updates and resume the work into subgroups in offline.  

Action items and needed updates for tomorrow’s discussion

• INTT offline timing calibration (Tony and Genki)
• INTT pool/decoder + towards streaming readout functionality (Martin, Raul, Sam, Dan, Chris)
• TPC/MVTX BCO matching efficiency + parallel event combining (Thomas, Joe) 

Date : Tuesday, Aug 14th after the SCM (presumably around 16:30 PM ET)
