sPHENIX HCal discussion

[Craig Woody <woody AT bnl.gov>]

Hi John L,
  I'd also like to express my personal thanks to John H for pulling off all three T1044+ events this year, but I really don't think that just personal thanks is enough. To me, this really deserves a medal, but unfortunately we don't give out medals in sPHENIX, but maybe we ought to.  I think something like this would be appropriate.
 




Some people really distinguish themselves above and beyond the call of duty, and this was really the case here.

Cheers,
Craig W (not to be confused with John H...)

Hi John,

    Many, many thanks to you personally for your dedication to the test beams overall, but this year in particular!

Thanks to help from Milap Patel, Jonathan Runchey, and Debbie Israel from Iowa State, we were able to complete what I hope is the final run of T1044 in 2018 with the combined energy scan of EMCAL (sPHENIX orientation), uninstrumented aluminum Inner HCAL frame, and Outer HCAL. The detector and instrumentation seemed to be in good order, but the analysis will be the final arbiter of that.  The beamline for these data was clear--T992 moved their apparatus out of the beam Saturday night and handed it over to us. The data are all at RCF and the index is here:

The haul by energy:

-28.0|1060434
-24.0|1066917
-20.0|1035363
-16.0|1049827
-12.0|1018710
-8.0|1548978
-6.0|1028393
-5.0|528847
-4.0|1041751
-3.0|518992
40.0|271795
50.0|201953
120.0|524953

Two things didn't happen that might have been nice... I was hoping to get a slug of data without the upstream material into the instrumented IHCAL; we have that data from 2018b, but I needed help with the crane to take out the IHCAL, so we couldn't fit more of it in this time.  Another thing that might have been interesting would have been if I had realized we might have been able to put the instrumented IHCAL behind the Outer HCAL when we put in the aluminum as a leakage detector... I didn't think of it until the steel was parked on the floor a few feet away.

But it's done, and the rest of the week should be quiet, no?
