Minutes of the forward endcap EMC meeting, 17th of July 2023, 14:00 - 14:45

Upcoming COSY beamtime (August 7th-14th):

• We will have beam from Monday, 7th, 8 am on until Monday 14th, 8am
• We will be able to work in the TOF area the two week before our beam time 24/7 while HBS is doing measurements in the Big Karl arae
• Accessible from outside during beam: T-settings (desired detector temperature, chiller), tube heaters
• Preparation plan before beamtime:
  • 1 h of fully open valves, then setting of flows in subcircuits
  • Light pulser tests
  • Baseline recordings
  • Synchornisation of light pulsers (TTL -> LVDS conversion)
  • Lukas' DAQ: Timestamp minimum frequency: 128 Hz
• Short view into SADC data (Christoph, Lukas): okay
  • VPTTs look good
  • APD thesholds too high (cutting cosmics peak)
