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

Minutes

Attendees: Bill, Sasha, Vlad, Hakob, Laveen, Ben, Olivia, Shane, Liping, Jane, Axel, and Igal

  • All bundles (100) of signal cables were installed between the VXS crates and the detector platform. The cables were pulled up to the platform and were positioned by the vertical cable managers, which will be installed shortly
  • 2 signal patch panels were populated with the LEMO connectors and were installed on the top and bottom of the detector dark box frame
  • After revisiting the design of the vertical cable managers for signal cables, we requested to install two additional cable trays to

route cables to the bottom patch panel.

  • Chris S. has approved the layout of the LV distribution box which will host the PCB with LV connectors. The LV boxes were outsourced; the manufacturing company also provided the design
  • We expect one student from the Jane's group to come to the lab in the end of September for about 5 months to work on the ECAL project*
  • We started discussing JEF presentation at the forthcoming DNP meetimng
