<p>Run 35 started.</p>
<p>D+ beam deuterium target. D+ beam energy is 2 MeV/u. (beam calc calculation is 1.9211 MeV/u -> may be wrong cooler voltage, need to check grafana)</p>
<p>Target density is about 4e12 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=-3.06, z=1.72 mm</p>
<p>YR09-Etarget pressure = 2.29e-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>Attachment 3,4 data rate to disk and statistics tab for when detector 4 is behaving. When not data rate can spike to 4000 kb/sec. Looks OK at the moment.</p>
<p>Attachment 5 - xy plot. We observe a circular shape on the detector. We are unsure of what this is at the moment. Offline analysis required.</p>
<p>Attachment 6 - energy histogram including Rutherford.</p>
<p>Attachment 7 - energy histogram just nuclear peaks.</p>
<p>Attachment 8 - beam calc with read values. </p> |
