<p><strong>22:56</strong></p> <p>Run 20 started - beam on target</p> <p>Beam energy is 1.5 MeV. Horizontal beam position = 7.0 mm, vertical beam position = 0.0 mm.</p> <p>Target density ~ 1e11 at/cm2</p> <p>Beam intensity at inj ~ 4e7</p> <p>Detectors are positioned IN. Left arm = 62.71, right arm = 64.60 mm</p> <p>Histograms and stats zero'd, monitoring code restarted.</p> <p>Beam in the ring ~ 3minutes.</p> <p>Pressure in YR09 E target ~ 4.5e-11 mbar.</p> <p> </p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before. OK</p> <p>FEE temperatures look OK</p> <p>System checks OK</p> <p>Leakage current stable</p> <p> </p> <p><strong>01:15</strong></p> <p>Target density has increased slighty: ~ 4e11 at/cm2 (update: this only lasted about 5 min)</p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before. OK</p> <p>FEE temperatures look OK</p> <p>System checks OK</p> <p>Leakage current stable</p> <p> </p> <p><strong>3:10</strong></p> <p>Target density has decresed slightly but will come back (hopefully) ~7e10 at/cm2.</p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before. OK</p> <p>FEE temperatures look OK</p> <p>System checks OK</p> <p>Leakage current stable</p> <p> </p> <p><strong>05:15</strong></p> <p>Target density has been somewhat unstable, between ~7E10 and ~3E12 at/cm2.</p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before. OK</p> <p>FEE temperatures look OK</p> <p>System checks OK</p> <p>Leakage current stable</p> <p> </p> <p><strong>07:37</strong></p> <p>Run continues. Target density still fluctuating around 1E11 atoms/cm2.</p> <p>Temperatures OK. Merger OK. Rates OK.</p> <p>System wide checks as before.</p> <p>Waveforms OK. See attachments.</p> <p>Some screenshots from the online analysis. We do not see a peak at 1 MeV. We do however clearly see more D than H2+.</p> <p>Stopping run to make some tests.</p> <p> </p> <p> </p>
