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 [12]
• Toook cosmic data with the whole detector powered [13]

• Temperature scan in the ECAL divider region [14][15][16]/4321188[17]

Meeting with Tim, additional fans will be installed

• Repairing a few ECAL LMS optical fibers [18][19]
• Preparing for the installation of the insulation on the detector face

- Removing Tedlar from the face of the detector [20]

- ECAL flash ADC scalers before removing detector face cover [21]

• Preparing for the run -- Sasha
