Subject:
<p>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.</p> <p>Attached screenshots and Ge spectra from before changing anything.</p> <p> </p> <p>run control = 49</p> <p>run data = /onlineNEDA_00/xData/hil099/run_0049_08-03-2023_09h31m08s/needleRU_i49_0049_0020.caendat</p> <p>RU = 13.3 MB/s</p> <p>LF = 6.15MB/s</p> <p>plunger:</p> <p>plunger run = 603</p> <p>actual distance = 382.7 um</p> <p>supposed distance = 382.7 um</p> <p>micrometer = 385.9 um</p> <p>position = 150.0 um</p> <p>voltage = 2.146 V</p> <p> </p> <p>Beam dump 0.7 nA</p> <p>Collimator ~1.5-2nA when the generator retunes itself (prob the beam gets defocused at those moments)</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p>
