Entry number 385769

I used a Sr-90 beta source and an analog readout card to check for response from the three thin Si planes A,B,D in the Compton e-detector. Bias voltage was 80V (which is 160 ADC ticks in the GUI).

Leakage currents at the start were

A  1036  398
B  1116  002
C   000  000
D  1505  001

I saw no response from my cable for "plane D left", but I did not try more than one strip there.

Plane A right

Plane A left

Plane B left

Plane B right

Plane D right
