AT, JLT,PC,AA | Clover, 133Ba, LN2 filling | We started the measurement of the source when the N2 filling started. Just to check if there are funny things
related to the filling.
Start: 18:45
Stop: 20:48
The source was in position z=0 cmm (no AIDA)

Ps. See that the pulser generates peaks in the region 250-270 keV (to avoid people to invent new levels (and
gammas) populated
in the beta decay of 133Ba). |

JLT,AT,KR,SG,RY,... | CLOVER 152Eu | 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

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.

Issues:
Pulsers of He006, He140 are tripled
There is a strange background above n-peak in He034
Calibration is ok except for He003, He004 and He006 !!!!
