sPHENIX HCal discussion

[Stefan Bathe <stefan.bathe AT baruch.cuny.edu>]

Dear All,

Here are the minutes from today’s meeting (also on indico).
We decided to have the meetings after the calibrations meeting, starting next 
Monday with two talks already on the agenda:  
https://indico.bnl.gov/event/20840/

Best regards,
Stefan

Minutes Oct 11 Calo Commissioning Meeting
    • Meeting after calibrations meeting (maybe bi-weekly?), separate agenda
    • Only calo experts, not EMCal vs HCal
    • HCal support during shutdown to assist TPC
        • Sharing among experts
    • Invite sEPD, ZDC/SMD, MBD
    • ADC repair re hot towers:  meeting:  Columbia, Colorado, Chi
    • LED:  Silas, Munir (see Monday’s calibration meeting), JaeBeom in touch 
with Munir regarding hot towers in LED → analysis discussion in calibrations 
meeting; link to Munir's talk from Oct 9:

        • Also talk by Emma from Sep 25:  
https://indico.bnl.gov/event/20659/contributions/81211/attachments/49967/85510/hcal_hot_towers_9_25.pdf
        • Find references and add to this agenda
    • Regular running of LED, TP, pedestal for both HCal and EMCal once per 
week (starting once ADC repair is done?) and discuss hardware health in this 
meeting
    • HCal hardware in good shape, no repairs needed (modulo ADC)
    • Hardware related pathologies in EMCal→future presentation by Anthony
    • EMCal South High Rapidity:  plan for instrumentation?
        • Eric:  sEPD order coming in, but not sure whether there will be 
enough boards
            • Coming in mid to late October (see Eric’s summary to DAQ list)
            • sEPD needs 12 boards, probably ordered 16, have 8 spares (makes 
total of 24), need 16 to complete high eta region, so should have enough; so 
the question is about repairs/replacements/spares
        • No contract in place to build more boards
        • Bill:  should be available for Run 3, but not Run 2
    • Eric:  EMCal:  one ADC crate with broken backplane (3C1, crate 3; i.e. 
NorthEast) will be replaced
    • Sean analyzing controller data (temperature)-->present
    • Anthony:  lowered SiPM cooling as a test to see whether single pixel 
peak can be re-gained→need analyzer (have code):  UIUC
    • Gain balancing→talk to Hanpu
    • Track task link from previous meetings:
