<p>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. </p> <p>There was also significant drift in the Ge gain (seen on the pulser) this may effect the shape of these peaks. </p> <p>Some gain drift was also seen on He preamps during this run. The cause is yet to be determined. It is also yet to be determined if these gain shifts are correlated. </p>
