Belle Stack 4: 2 DSSD -z, Origami #3, #1, wedge new #2
HV = +-50V, Ibias=80A
Position: approx. centered
no beam
Total bias current history:
At the beginning, the system was already running for a few hours and the APV25 chips were initialized before, so thermal equilibrium was reached.
The actual calibration run happened during the first ~250 measurement points (~1 hour). It seems like the APVs draw a bit more current during internal calibration. The overall decay is supposedly due to a temperature decrease towards night.
Now tried the same thing with a short software run - same effect:
Need to investigate supply currents while data taking - they should actually go up a bit - and their dependency on the trigger rate.
