Agenda

  • Preparation of parts for ECAL -- Sasha
    • - signal cables - done
    • - signal patch panel [1] - done
    • - HV short cables: received, checked, labeled (last week)
    • - HV long cable, 18 ready (out of 36)
    • - HV distribution boards: in preparation
    • - LV cables: 100 cables received, 640 cables in total
    • - LV distribution boards [2]. Have to populate with connectors, and design a box around the PCB
  • Ongoing projects -- Sasha / Vlad / Hakob / Laveen
    • - Tested and labeled all HV cables ! and about 100 LV cables [3]
    • - Bundling short cables (groups of 7, 7, and 6 cables)
      • finished: LV - 13 layers, HV - 18 layers, signal - 9 layers (40 in total out of 120) [4][5]
  • Testing of PMT dividers -- Sasha / Vlad / George
    • - Testing procedure [6]
    • - About 1420 dividers have been fabricated (Chris, Armen, Mindy)
    • - Started removing power regulators on the newly fabricated dividers
    • - George has recently tested 142 dividers (1063 have been tested in total) [7].
    • - Adding ECAL (and updating FCAL) translation table in the TT.DB (needed for EPICS scalers)
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen
    • Preparing safety documents. The following ePASes have been submitted and approved -- Sasha and Vlad
      • Installation of the ECAL LMS
      • Installation of cables and dividers,
      • Beam tests with the PS test setup
      • Preparing ECAL cables (EEL126)
      • Fabrication of calorimeter prototypes (EEL126)
      • Testing ECAL dividers (EEL118) (approved in January)
    • Installation of the LMS
      • 1132 fibers have been installed [8]
    • Cable and divider installation [9][10][11]
    • Power installation on the platform has been completed [12]
    • Detector installation page
    • Other hardware projects
      • --prototype of the ECAL veto counter
