Meeting time and location:


Agenda

Preparation of parts for ECAL -- Sasha

  • - HV long cable: Sammy and Mindy are finishing up with assembling cables, 2 cables are left
  • - HV distribution boards [1][2]
- 5 (12 x 4) and 5 (6 x 8) boards have been received. Chris checked connections. All remaining PCB boards are expected to be in the lab on Sep 12.
- Chris is finalizing design of the distribution boxes (each box will comprise 9 PCBs). He expects to submit PR during next week.
  • - Fix front panel of two LV distribution boards [3]
- new plates for the LV distribution boards should arrive today. Need to re-install 2 distribution boards and connect cables

Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen

  • Installation and testing dividers has been completed [4]
- need to arrange cables on chains
- need to arrange cables on cable trays - done [5]
- preparing spare cables (7 short HV, 8 signal and LV)
- Installing HV distribution boards (start switching the detector ON)
- Installing dark room ceiling and insulation inside the room
- Checking cooling system

Students -- Sasha

ECAL commissioning -- Sasha, All
