Agenda

Preparation of parts for ECAL -- Sasha

-New PCB and parts for the LMS light source arrived to the lab. The LMS board will be assembled and tested during next week.

-Consider to install two more temperature sensors (will try to fix the old ones first), a few sensors have been ordered

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

• Implementing ECAL into the GlueX DAQ [1]

- Initial version of the VTP firmware ready. Started testing using a setup with one VTP during the holiday break (some progress has been made)

- VTPs installed on all ECAL VXS crates [2]

- Use new version of DAQ, VTP included as a DAQ component. Will be updated on the entire detector after the ECAL commissioning

• ECAL HV interlock check [3]

• All HV distribution boards have been installed [4] [5] [6] [7] [8]

-Replace one HV module (problems with the interlock) [9]

• Update signal translation table [10]
• Update mapping of the ECAL high voltages and spare HV cables [11]
• Implement ECAL HV interlock based on the newly installed temperature sensors in the divider region
• Toook cosmic data with the whole detector powered [12]
• Temperature of the ECAL modules

Previous temperature scan in the ECAL divider region [13][14][15]/4321188[16]

ECAL commissioning -- Sasha, All

Calibrations

• Gain calibration
• Low-level timing
• Timing with respect to other detectors

Analysis/Simulation
