| <p>Run 47 started. Target cooling down after water cooler failure, beam only background</p>
<p>D+ beam deuterium target. D+ beam energy is 0.5 MeV/u. (beam calc calculation is 0.5143 MeV/u). See previous entry for beamcalc.</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 10 seconds.</p>
<p>Cooler set value = 297.2 V, 8 mA. Read value = 296.477 V, 6.97 mA</p>
<p>All leakage currents look good (except dssd4, currently stable at V=40)</p>
<p>Beam position. Vertical =0.0mm , Horizontal=0.0 mm</p>
<p>Data rate ~ 25kB/s</p>
<p>13:00</p>
<p><strong>Run stopped </strong>to allow tuning of parameters for 0.35 MeV/u</p> |
