Commissioning and running of sPHENIX

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

Hello Vernier-Scan-Interested-People,

Here are the set Values from Angelika Drees from the Vernier Scan done last Thursday, July 11, 2024.

The data taking during that scan corresponds to run number 48029.

A few notes that were posted in MatterMost:

Angelika ran the Vernier Scan, and everything went very smoothly. Sasha Bazilevsky, Cheng-Wei, Kin and I were in MCR and Virginia and Martin coordinating in 1008. The issue of not having trigger 0 (Clock) was "solved" by putting trigger 5 into GL1P slot 8. Trigger 5 is called the "HCal Coincidence", but when not connected, it runs at the clock frequency (9.38 MHz). Thus, that GL1P slot 8 should provide the needed livetime bunch-by-bunch across the scan. It will be very good to get a detailed report from these scalers that this solution worked and thus will work for additional Vernier Scans later this run.

Sincerely,

Jamie
