Meeting time and location:

Agenda

  • Preparation of parts for ECAL -- Sasha
    • - HV long cable, 18 ready (out of 36), discussion with the DSG group regarding help
    • - HV distribution boards: has not yet been designed, need 4 boards
    • - LV cables: missing about 20 cables, waiting for the last delivery batch.
    • - LV distribution boards [1]. One board out of 4 is ready, using for testing dividers Media:lv_distribution.jpg
    • - LED: prototype board is ready, have to start testing
  • Ongoing projects - All
  • Testing of PMT dividers -- Sasha / Vlad / George / Mindy
    • - File:Regulators.xlsx Map of dividers with removed regulators
    • - Testing procedure [2]
    • - All dividers have been fabricated and tested by George [3]
      • Continue removing regulators from the PCB (about 70 regulators have been removed, require re-testing dividers)
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen
  • Summer students -- Sasha
    • - Olivia, Ben, and Shane are on site. Expect one student from Wuhan (have to start with the paperwork)
    • - Projects: document all test results, assist with the cable/divider installation, install signal cables on patch panel, work on the ECAL monitoring plots
  • Beam tests with the PS
      • measure shower beam profile and reconstruction in the crystal/LG transition region
      • (install prototype with 5x5 PbWO4 modules + ? LG)
  • Other hardware projects
    • prototype of the ECAL veto counter (?)
  • FCAL2 posters for open house** File:1-OH24-Poster-H-Laveen-revised4.pdf
  • Analysis/Simulation
