sPHENIX cold QCD topical group

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

Hello  ZDC peoples (cc cold QCD),

After getting multiple inputs / viewpoints, I have decided that we will not move the ZDCs from their current positions.     We need our focus of experts to be in many other areas (including  TPC isobutane, etc), and leaving our luminosity counters as they are is a simplifying effort.

I know there may  be some concerns if the polarization is not vertical, but there are many reasons to believe this is not the case --  and likely not possible.     However, since we had a situation where the EMCal was unavailable last night, I instructed the shift crew to take a set of ZDCNS triggered runs.     It would be great if people can check these high statistics runs for vertical polarization and report at one of the upcoming SCM.

Run 48445, 48446, 48447.

Sincerely,

Jamie
