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