Agenda

Preparation of parts for ECAL -- Sasha

  • - HV distribution boards [1][2]
- Connectors and cables were installed on the PCBs of 2 HV distribution boards. Sammy and Chris are working on the third board, it will likely be ready during next week (Sammy also works on GEM/TRD)
- Boxes for HV boards have been just been ordered. Expected delivery date 11/15/2024.
- Vince P. has machined parts for two temporary distribution boards. Two temporary HV distribution boards were assembled. The holes for connectors were too narrow, the tech group fixed it.
- Have received all parts for the new version of the LMS light source

Installation of the FCAL2 detector & integration to GlueX -- Sasha, All

  • Installation of the light distribution board of the ECAL LMS [3]
- Vlad P. has slightly modified the design of the LMS light source in order to increase the amount of light. Chris S. is working on a new board with 9 LEDs.
  • Implementing ECAL into the GlueX DAQ [4]
- rocecal3 crate was fixed [5] (initial DAQ implementation [6])
- implementing flash ADC scalers [7][8]
- translation table for the ECAL (finalize/check translation DB, generate xml file, import to the CCDB) - done [9]
- implementing and verifying ECAL LMS trigger [10]
- implementing and verifying the ECAL physics trigger. First event reconstructed using the GlueX software [11]
- Start implementing VTP trigger modules. Requires modification of firmware. The trigger crates may be unavailable for 1 - 1.5 months.
- The VTP was installed in the D2-1-TOP crate, IP address assigned, and can be booted now
- Connecting cooling pipes to the ECAL fan (done by tech group)
- Installing dark room ceiling and insulation inside the room, required for cooling test (almost complete)
- Test cooling system (in progress, almost complete)
- Installing HV distribution boards, start switching the detector ON (waiting for HV boxes)

Restoring PS test setup [20]

ECAL commissioning -- Sasha, All

Calibrations

Analysis/Simulation

Laveen Update

Presentation at IEEE [21]

Conference trip was not supported by Hall D
