<p>DSSD4 has been biased to 100V in steps of 5V from 60V. It was previously stable overnight at 60V - attachment 1</p>
<p>Will keep an eye on it but looks OK at the moment. Current bias and leakage current - attachment 2</p>
<p>I have reset DSSD4 FEES (13,14,15,16) to the LEC and lowered the thresholds to be in line with other FEES.</p>
<p>Current slow comparator threshold for all FEES is 0x14 (200 keV).</p>
<p>Attachment 3 shows current ADC data items statistics.</p>
<p>Started a new run 51 with no beam and no target. Access to the cave is allowed.</p>
<p>Current data rate is 800 kB/sec.</p>
<p>All statistics and histograms in aida zero'd</p>

<p>Temps OK</p>
<p>Rates OK - attached</p>
<p>Merger OK</p>
<p>System wide checks</p>

<p>Temps - OK</p>
<p>Rates - OK</p>
<p>Merger - OK</p>

<p>Beam tuning to start soon. No storage.</p> |
