All four detectors positioned fully out and stationary,</p> <p>I tried to re-bias detector #4 however was not able to bias past 70V. DSSD4 remains off and set to the MEC (0x1). (see attchement 1)</p> <p>Ring cycle is every 10 seconds. Beam position unchanged, Beam position. Vertical =0.0mm , Horizontal=0.0 mm</p> <p>Ring vacuum is now 3.16e-11 mbar. Before switching off the gas target density was 2e12 at/cm2</p> <p>Data rate is 89 kB/sec</p> <p>ADC data items stats remain largely unchanged at new threshold. (see attachment 2)</p> <p>Aida01 has increased to several thousand. Tried check ASIC control on asic #4 of aida01->no effect on higher rates.</p> <p>01:20</p> <p>All checks OK.</p> <p>After 20 minutes of running see energy histogram and xy histogram (attachments 3,4)</p> <p>Interesting xy pattern (hydrogen? Injection noise?)</p> <p>Note put aida13-aida16 slow comparator threshold back to 0x24 as we had some rates coming through (~1kHz) which is now back to zero. If we revive the detector in the morning, the thresholds should be lowered in line with other detectors.</p> <p>03:00</p> <p>All checks OK</p> <p>04:30</p> <p>All checks ok</p> <p>7:20</p> <p>All checks ok</p> <p><strong>Run stopped</strong>, final energy histogram and xy histogram attached.</p></td> </tr> </tbody> </table> </p><p> </p>
