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.

run control = 49

run data = /onlineNEDA_00/xData/hil099/run_0049_08-03-2023_09h31m08s/needleRU_i49_0049_0020.caendat

RU =  13.3 MB/s

LF =   6.15MB/s

plunger:

plunger run = 603

actual distance =  382.7 um

supposed distance = 382.7 um

micrometer =   385.9 um

position =  150.0 um

voltage =  2.146 V

Beam dump 0.7 nA

Collimator ~1.5-2nA when the generator retunes itself (prob the beam gets defocused at those moments)
