A file with Co and Cs was collected for 10 min

201905201444_137Cs60Co_align.root

after a minimal correction of the voltages (mentioned in the earlier entry). After this a new calibration was performed.

Rates per detector of the order of 1.7 kHz, Ref det rate 63 Hz, with the pulser set to 10 Hz

Now a  check on the other available sources will be performed.

Until now the used Co source was CO401(2530) , which is rather strong (corresponds to key 6)

and the Cs source was CS401 (4763) (key 8). This Cs is fine.

Now the sources on the red box (color ?) will be explored.
