<p>Run 29 started. Beam energy is 1.3435 MeV/u with a cooler voltage of 751.3 V.</p>
<p>We observe significantly greater count rate for top right detector (DSSD#1) now that the beam energy has been lowered. ADC over range? Beam target overlap change?</p>
<p>Plan to check optimisation of beam-target overlap and beam settings again.</p>
<p>12:40</p>
<p>Beam lost. Detectors out. R29_11</p>
<p>13:37</p>
<p>Electron cooler is not working again. We will have un-cooled beam again.</p>
<p>Will start a new run 30 for un-cooled beam on target.</p> |
