Commissioning and running of sPHENIX

[Jamie Nagle <jamie.nagle AT colorado.edu>]

Hello All,

The issue of BCO matching and dropping data has reached a critical point and to help converge on resolving these issues,

we will have a meeting on:

Date:    Monday, August 5, 2024 at 1:30 pm ET
Zoom:   https://bnl.zoomgov.com/j/1614645041?pwd=bmE4STBRZk5tVVVUUC8zRnQxSlFyQT09
Google Doc page:    https://docs.google.com/document/d/1UqPhHGo4_B-ws8nlGrg8Mkc7jGHtZGeja1LBL7luhq8/edit

I realize that everyone may not be available at that time, and JaeBeom will coordinate the meeting.      This meeting pertains to the INTT, MVTX, TPC in both triggered and streaming readout modes.     

One critical topic is resolving remaining questions about INTT BCO matching and dropped data.     The same issue is going to apply to the full streaming TPC readout.     Raul if you can provide a couple of slides demonstrating for the INTT that there is BCO data even when there are no hits, that would be great -- we discussed this some time ago, and there still appears to be confusion.    There are also the different levels where the BCO is copied.    Martin, can you  show what information is now available in offline (and whether we are missing information that is in the PRDF)?     At this point, we really need all information available in offline --  this is time critical.

We need to better understand the checks in Online Monitoring, in Offline QA/Reconstruction.      At some point it seemed we were close to demonstrating in OfflineQA that we had all detector components corresponding to a given GL1 trigger, and had track rates for MVTX & INTT - but that seems to have lost momentum.    

This is time critical.      We cannot continue taking data without knowing if it is decodable and if we have a complete detector set for a majority of events (at a minimum).     Please let me and JaeBeom know if you will provide slides (in advance is best, fully labeled, and with details on how they are made).      

Sincerely,

Jamie
