    keyword=Compton e-detector: response to Sr source from three thick planes

    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.

    Resubmitted with correct attachment filetypes.






    Plane A right



    Plane A left



    Plane B left



    Plane B right



    Plane D right
