Sr90, large scintillator,
HVret @ Origami closed
HVret @ SMU connected
Origami Mod. #4
HV=+-40V, Ibias=1,6µA
CO2 cooling on, Tin=-20.5°C, Tout=-21.5°C

I²C settings for cooled APV chips --> same as used in run010

e:\cvi-projects\apvdaq_fadc\origami6_V2_multi6_cooled.cfg

Lab measurement with new dark box but old, large scintillator

Wires between HV connectors ground and HVret conntact at the mambo were open --> no HVret conntection between module and SMUs!
Moreover the SMU Inv. Nr. 545-078 has either an unstable output or problems with the current measurement.
