Agenda

Preparation of parts for ECAL -- Sasha

• - HV distribution boards [1][2]

- PCBs with 5 (12 x 4) and 5 (6 x 8) connectors are ready for two distribution boards. One more board will be ready during next week.

- Boxes for HV boards have been ordered. The lead time about 3 weeks.

- Communicated with Vince P. (JLab's machine shop) and Tim. Ordered 2 temporary distribution boards, if the delivery of the real ones is delayed

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

• Installation of the light distribution board of the ECAL LMS [3]

- Fine-tune the light source. Slightly modified the design, ordered new LEDs

• Implementing ECAL into the GlueX DAQ [4]

- rocecal3 crate was fixed [5] (initial DAQ implementation [6])

- implementing flash ADC scalers [7]

- translation table for the ECAL (finalize/check translation DB, generate xml file, import to the CCDB) - done [8]

- implementing and verifying ECAL LMS trigger [9]

- implementing and verifying the ECAL physics trigger. First event reconstructed using the GlueX software [10]

- Installation of scintillating paddles for cosmic tests [11]

- Start implementing VTP trigger modules. Requires modification of firmware. The trigger crates may be unavailable for 1 - 1.5 months.

• ECAL HV interlock check [12]
• Cable map of the ECAL LG modules after installing ECAL [13]
• Reinstalling cables on the ECAL LV distribution board [14][15]
• Safety briefings - Vlad, Sasha
• Detector installation page
• FCAL2 Engineering Meetings
• Remaining installation tasks

- 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 [16] ECAL commissioning -- Sasha, All

• Calibrations
• Analysis/Simulation
