We connect the pulser to both CLOVERs G7: It looks OK except for the G7-Green as before (there pulser peak in the spectrum) D4: the pulser peak appears at very low energies (200-600keV) there seems to be a problem with pulser processing in the preamplifiers. Should we still use it? We remove for the moment. 152Eu source calibration. We put the 152Eu source at the center (on the cardboard) and check de energy calibration. For most of the crystals the calibration from March was pretty good except for D4-Red that the gain changed by a factor 1/2 and D4-blue that changed by 2 (!?) We redo the calibration: G7: the resolution at 1.4MeV is 2.7keV D4: the resolution at 1.4MeV is 3.9keV DLT File; 170525_0947_152Eu_z0cm.root_000.dlt RUN Number; 000 RootFile: 170525_1034_152Eu.root Comments: rate of the clovers increased from 2000cps to 2400cps for 10 min (from TS = 41.8E6 ms to TS = 42.4E6 ms) We plugged the pulser in clover D4.
