Minutes of the forward endcap EMC educe SRN meeting, 15th of August 2016, 14:00-14:30

Presence:

  • Basel: excused.
  • Bochum: Cathrina, Claudius, Fritz-Herbert, Matthias, Tobias H., Tobias T.,
  • Bonn: Christoph
  • Giessen: -
  • Groningen: -
  • Stockholm: -
  • Uppsala: Pawel
  • GSI: -

SADC (Pawel)

  • Gain was modified for Basel preamp input of 2V and gain ratio 16. Different filter parameters implemented and tested with TI pulse generator. See attached file ADC_Gain_Resp_Noise.pdf. X-axes in 12.5 ns samples.
  • SADC will be sent to Bochum tomorrow

Bonn news (Christoph)

  • Voltage regulators, I2C irradiated under voltage with 125 Gray
  • Got quote for HV cables (1000 cables, each 60 m)
  • Production of pitch adapter for SADC cables
    • need to define length of signal cables, uncertainty due to variation of cooling line placement (< 10 cm)
    • need mockup of PCB backplane for SADC (What is the status, Myroslav?)

LV distribution (Claudius)

  • combine LV for up to 9 patch panels/subunits (decision)
  • shielded LV cable identified. To be ordered (by Claudius) and irradiated

Glueing tests (Matthias, Claudius)

  • glueing test with crystals from Giessen ongoing. Do temperature cycles for 7 days.

Miscellaneous

  • Does anybody has old Basel APD preamps available (Matthias)?
  • New test setup for Bonn ready in 2 weeks (Tobias H.)
