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.)
