Minutes of the forward endcap EMC meeting, 10th of Novemberr 2014, SeeVogh, 14:00-15:00

Topics are not in the order of discussion, but by subject.

Presence
  • Basel: excused
  • Bochum: Claudius, Fritz-Herbert, Mario, Miriam, Patrick, Stephan, Tobias H., Tobias T., Tom
  • Bonn: Christoph, Ulrike
  • Groningen: Myroslav
  • Uppsala: -

Electronics
  • Christoph: new test module with shaper is ready and will be sent to Bochum next Wednesday.
  • Myroslav: Newest ADC received from Pawel last week. Will take a few weeks for software/testing etc.

Cables
  • Christoph: Quotes available. Order signal cables (16 weeks production time), order HV cable (delivery week 7/2015)
  • Christoph: low voltage: examples to RUB. HV cables for VPTT will be ordered, HV for APD rated 300 V.
  • Fritz-Herbert: Cables for alveole should be ordered, such that VPTT alveole mass production starts latest in January.

Mechanics
  • Myroslav: RUB got all swagelok connectors from KVI. Action: Rick will sent a list with all required types (and order numbers) in the next few days.
  • Christoph, Tom: Action: Inserts, mount plates and alveoli can be transported to Bochum by car (driver from Bonn University) whenever possible.
  • Myroslav on crate design: New ADC has components on both sides. Will work on how to cool in the next few weeks.
  • Claudius: Depth of crates? Myroslav: 10cm = height of ADC module, additional space for backplate and connector. Rest available for cables.
  • Myroslav: Hydraulic pads for endcap are in principle commercially available. No detailed design was done by Michel.

Photodetectors
  • Christoph: More measurements of VPTTs@0.99T, theta=0 and HV=1000V performed. Reduction of gain due to mag. field to about factor 0.4-0.5. 30 VPTTs measured/week. Action: Christoph will sent around results after next measurements (Due date: next Tuesday). After that will do final decision on preamp gain for VPTTs.
  • Ulrike: What is the status of the APDlab measurements? Do we need to irradiate all APDs? Fritz-Herbert: Please ask Andrea about details.

AOT
  • Rauischholzhausen attendance: Myroslav possibly, Bonn: Andrew, Christoph, Bochum: Tom, Claudius, Patrick, Tobias T., Tobias H. , Fritz-Herbert
