Minutes of the Forward Endcap EMC Big Blue Button Meeting, 7th of February 2022, 14:00-14:30

Submodule Production:

  • We established a test stand built around a climate chamber using the mobile teststand for the Juelich installation
  • Its purpose is detecting malfunctions of submodules only occuring at the operation temperature of -25 degrees C rather than at laboratory temperature
  • A channelwise HV regulation will also be implemented
  • There is one submodule delivered to Bonn that obviously shows much too high response. The stated HV settings seem commonly to be too high by about 10 V each.
  • Looking at the data corresponding to the APDs in this submodule there is nothing ununsual looking. Currently we have no idea where this comes from.

FWEC Cabling:

  • Vinee and Christoph will once again come to Bochum (Tuesday next week) in order to finalize measurements of the cable length on the detector
