HPGe fill line to D4 replaced only small leak (overflow) once Ge is full.
Solenoid was also wrapped to no effect. AIDA DAQ still stops writing.
Boron sheet and extra polyethylene were placed back on top. |

Sat Nov 5 03:18:13 2016, SG BCR RCF NTB, Gamma peaks in the overnight run, related to neutron inelastic scattering
|
We looked at the overnight background run (161105_0935_BackgroundOvernight.root), There are gamma-peaks that could be related to neutron inerastic
scattering. We identified 565, 596, 608 and 69 keV. They might be related to the effect of neutrons. If this is the correct assignment, this would mean
at least some of the neutrons are not thermal when they interact with the germanium. |
