After the long shutdown the beam is back at 00:30 (06/05)
Intensity is slightly lower 26pnA and somewhat unstable (short time)
Measurement in the morning:
File: 150506_0846_0915_94Se.root
Average rate per tube (n/s): U=3.39 D=0.93B=0.40
Notes:
-The rate has increased by 3.5 in the detectors close to EURICA (!?)
-The rate at the detector below the MUSIC is substantial.
From the different magnitudes it is clear that neutrons are originated
both outside and inside EURICA. |
