<p>22:49</p> <p>Run 37 started.</p> <p>D+ beam deuterium target. D+ beam energy is 2 MeV/u. (beam calc calculation is 1.9211 MeV/u)</p> <p>Target density is about 1.3e12 at/cm2. FLuctuations between 1e12 and 1e13 at/cm2.</p> <p>All four detectors positioned fully out and stationary.</p> <p>Left potentiometer = 18.86 mm</p> <p>Right potentiometer = 19.8 mm</p> <p>Ring cycle time is 1 minute. Note we see some hydrogen in in the spectrum, this disapears after a few seconds.</p> <p>Target T1=30K, T2=31.9K.</p> <p>Nozzle position x=-3.11, z=1.77 mm</p> <p>YR09-Etarget pressure = 1.04e-10 mbar.</p> <p>Cooler set value = 1126V, 15 mA. Read value = 1068V, 13.22 mA</p> <p>Detector 4 is still a bit unstable in its leakage current but the data coming through looks good. Some crap is periodically written to disk when leakage current spikes. Attachment 1,2 for leakage currents.</p> <p>23:30</p> <p>Checks OK - high but managable rates from DSSD4</p> <p>01:00</p> <p>Checks OK - DSSD4 has settled down. Leakage current attachment 1</p> <p>Ex energy histograms - attachment 2</p> <p>X2go check on gas target shows density has dropped to 5e11 at/cm2 in last half an hour. </p> <p>03:56</p> <p>Checks OK</p> <p>DSSD had more issues but once more settled</p> <p>Temps OK</p> <p>Rates OK</p> <p>DAQ continuing</p> <p>06:00</p> <p>Checks OK</p> <p>08:00</p> <p>We can now change to 1.5 MeV/u no storage mode enabled. </p>
