Counting rates continued to increase (det4 > 3kHz). Beam current looked fine on the beam dump, but beam is fluctuating, and can reach 2nA on the collimator. 
Asked for improved focusing.

Attached screenshots and Ge spectra from before changing anything.

The beam was unstable from 7:55. Stabilized around 8:03.

Counting rates are higher, EAGLE det4 went to ~2.5kHZ from ~2kHz (attached).

According to the operator, a bit of a tuning was done, current is 1nA.
