Fast discriminators turned OFF for all channels by setting enable mask in discrinator control to 0xfffff. See attachments. </p> <p>D+ beam deuterium target. D+ beam energy is now 0.2 MeV/u.

We may have to look at lowering target density</p> <p>Attachment 25 shows IPM with no target and attachment 26 shows IPM with the target 8e12 at/cm2. Compare also to attachment 12 (IPM with target at 2.6e12). </p> <p><strong>14:20</strong></p> <p>Checks are ok!</p> <p><strong>15:25</strong></p> <p>Fees 13-16 switched to MEC and bias on DSSD4 switched off</p> <p>All other checks ok</p> <p><strong>17:00</strong></p> <p>Target dropped to 1-2E12 atoms/cm2</p> <p>All checks okay- 17:25</p> <p><strong>17:45</strong></p> <p>Moved nozzle from x=-1500 to x=-2000, density went from 1E12 to 3E12</p> <p>Moved nozzle again at 18:00 from x=-2000 to x=-3000 in steps of 500, density at 4E12</p> <p><strong>18:45</strong></p> <p>Turned bias ON for dssd4 stable at V=10 but unstable at V=20 so bias turned back OFF</p> <p><strong>19:30</strong></p> <p>All checks ok!</p> <p>IPM attached, target density 2.6 atoms/cm2 (attachment 12)</p> <p><strong>20:00</strong></p> <p>Tried moving the nozzle more as target density dropped to 2-3E12 again</p> <p>Moved in 500 steps either side of x=-2500 but didn't improve, then moved in 100 steps from y=1600 to y=2300 and target density now 6E12 at x=-2500 and y=2300</p> <p>Tried dssd4 again but only stable to V=20 so bias OFF </p> <p><strong>21:50- </strong>All checks good, target density stable at 8E12</p> <p><strong>22:50-</strong> All checks fine (see attachments), target density at 6E12</p> <p><strong>00:10</strong></p> <p>Checks OK. Have zero'd statistics to see pause and resume statements over an hour.</p> <p>Rates looks OK. ~140 c/h 3He, and ~80 c/h for 3H and 1H each.</p> <p>Target has been stable at 7e12 at/cm2 for the last hour. </p> <p><strong>02:10</strong></p> <p>Checks OK.

Restored display from remote access by M.L.</p> <p> </p> <p><strong>11:22</strong></p> <p>Storage data stopped and Faraday cup inserted to check the leakage current of Detector #4. Not good, current increases above 10 uA already at 40 V. </p> <p><strong>11:29</strong></p> <p>HV Detector #4 swithced off, Faraday cup removed, data stored again.</p> <p> </p> <p><strong>11:35</strong></p> <p>Check OK.

No response for rates either. Merger looks fine for 3? Likely just happened.</p> <p>Attempted to STOP the DAQ. All FEEs still going (refused to stop) and 3 in error. Decided to just turn all FEEs off.</p> <p>Restored DAQ with no issues. 3 is working. Temperatures fine. Rates fine. Unclear what had happened.</p> <p>Run59 is EMPTY.

Changed cooling by 0.5V. Significant improvement in the IPM, but Rutherford goes down. Target missed?</p> <p>Changed orbit bumps. Increased Rutherford. IPM is back to how it was. Rates are possibly slightly higher? Will attempt more systematically in the afternoon, when we change beam energy again.</p> <p>Attempted to delay target on by 1 second. No significant changes in beam lifetime or rates. Can try systematically again in the afternoon.</p> <p>Restored settings to how they were.<strong> Started new run 61.</strong></p> <p>Temps OK</p> <p>Rates OK</p> <p>Merger OK</p> <p>Online histos look OK (did not reset)</p> <p> </p> <p>Checks</p> <p>Clock status</p> <p>FEE64 module aida16 global clocks failed, 6<br /> Clock status test result: Passed 15, Failed 1</p> <p>ADC calibration</p> <p>FEE64 module aida16 failed<br /> Calibration test result: Passed 15, Failed 1</p> <p>White Rabbit decoder</p> <p> <br /> Base Current Difference<br /> aida14 fault 0xbf08 : 0xbf08 : 0 <br /> aida14 : WR status 0x10<br /> White Rabbit error counter test result: Passed 15, Failed 1</p> <p>Understand the status reports as follows:-<br /> Status bit 3 : White Rabbit decoder detected an error in the received data<br /> Status bit 2 : Firmware registered WR error, no reload of Timestamp<br /> Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR</p> <p>FPGA Timestamp error counter test result: Passed 16, Failed 0</p> <p> </p> <p> </p></td> </tr> </tbody> </table> </p><p> </p>
