APD-Submodule Material Bonn:
About 1800 signal cables produced. To be shipped to Bochum. Bonn used an upgraded machine, which will be sent back. They will get a new one in one month.
Deliveries from Bonn arrived in Bochum.
Voltage range HV regulation
Each APD can be regulated separately. Currently with a voltage range of 30 V and steps of 0.1 V. It was agreed to change this to a maximum range of 15 V and 0.05 V steps.
The measurement has currently a resolution of 100 mV (due to thermal dependicies of the resistors.).
Status SADC backplane and power supply
Backplane PCB in production (soldering). Expected this week.
Power supply expected soon (1pc to test).
Power supply evaluation model did not survive irradiation test. Waiting to cool down for more checks. It might be due to the high intensity (1011 p/100 s). Next irradiation is planned for June 28 with a lower intensity.
Status of the crate is unknown (check with Myroslav).
FEE and DAQ workshop
Starts Monday, May 27th at 2:00 pm and end on Wednesday, May 29th at 12:30.
