Agenda

Preparation of parts for ECAL -- Sasha

-Four boxes for HV distribution boards have arrived to the lab. PCBs with HV connectors were installed on 2 distribution boards [1][2]

-Updated design of the LMS light source with 25 LEDS. PCB layout under preparation, expect to order the new PCB during next week.

-Two additional fans for cooling the ECAL dividers arrived. Will be installed today.

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

• Implementing ECAL into the GlueX DAQ [3]

- rocecal3 crate was fixed [4] (initial DAQ implementation [5])

- implementing flash ADC scalers [6][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]

- 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

- New version of DAQ, VTP included as a DAQ component [11]

• Installation of scintillating paddles for cosmic tests [12] [13][14]
• ECAL HV interlock check [15]
• Cable map of the ECAL LG modules after installing ECAL [16]
• Reinstalling cables on the ECAL LV distribution board [17]
• Safety briefings - Vlad, Sasha
• Detector installation page
• Commissioning north part of the ECAL (instrumented with 2 temporary HV distribution boards) [18][19][20][21]
• Commissioning of the south bottom region [22]
• Commissioning of the south top region [23]
• Fix LV issues (north top region) [24]
• First cosmic event in the ECAL [25]
• Temperature scan in the ECAL divider region [26][27][28][29]

Temperature of the NPS detector

[30] -2 temperature sensors in the divider region connected, fan included into the detector interlock -- Josh, Bobby

Meeting with Tim: More powerful fans will be installed in the inner region. Beam pipe can be cooled, need specs and technical details (decided to put on hold). Can operate the chillers at smaller temperatures.

• Repairing a few ECAL LMS optical fibers [31][32]
• Preparing for the installation of the insulation on the detector face

- Removing Tedlar from the face of the detector [33]

- ECAL flash ADC scalers before removing detector face cover [34]

• Preparing for the run -- Sasha

Page for shift Takers

ECAL in the Experimental Safety Assessment Document (ESAD)

EPAS for Maintenance of the Hall D ECAL (Jlab-PTW-5236)

• FCAL2 Engineering Meetings
• Remaining installation tasks

- Installing additional fans (will be installed today)

- Installing insulation on the detector's face (done)

Restoring PS test setup [35]

ECAL commissioning -- Sasha, All

Laveen update[[36]]

Calibrations

-First look on cosmic data -- Zhikun

-Adjusting HVs
