<p>Run 40 started cooled beam on target</p>
<p>Detectors IN (left arm pot =36.5 mm, right arm pot = 70.49 mm). Stationary. Same as run 35</p>
<p>Electron cooler voltage 751.095 this corresponds to 1.338 MeV/u. This should be on the left of the peak of the resonance.</p>
<p>Target density is 4e11 at/cm2, ring pressure looks OK YR09 1.43e-10 mbar.</p>
<p>Horizontal beam position is -7.5 mm, vertical beam position is 0.0 mm. Same as run 35.</p>
<p>Beam is in the ring for 4 seconds and total cycle time between injections is 8 seconds. Notice this is different than run 35.</p>
<p>Statistics, merger statistics, histograms all zero'd</p>
<p>15:39</p>
<p>System wide checks ok. Merger ok. Temperatures ok.</p>
<p>Attatchment 1: statistics</p>
<p>Attatchment 2: Temperatures</p>
<p>Attatchment 3-6: Waveforms. Layout 2 - (attach 4) had a strnageish waveform for aida11, stays after reload.It was the HEC firing so did an ASIC control and Zero'd histograms and all is okay.</p>
<p>Attatchment 7: Leakage current</p>
<p>17:04</p>
<p>System wide checks ok. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly.</p>
<p>Attatchment 8: statistics</p>
<p>Attatchment 9: Temperatures</p>
<p>Attatchment 10-13: Waveforms. Everything looks ok.</p>
<p>Attatchment 14: Leakage current</p>
<p>18:55</p>
<p>System wide checks ok. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly.</p>
<p>Beam transformer shows a small decrease in beam intensity, not drastic but small slow decrease, see attachment 22. Target density 4e11. Vacuum pressue ok.</p>
<p>Attatchment 15: Statistics</p>
<p>Attatchment 16: Temperatures</p>
<p>Attatchment 17-20: Waveforms</p>
<p>Attatchment 21: Leakage current</p>
<p>19:28</p>
<p>Run40 - Beam dropped intesntiy at 19:17, moved detectors out, called gleb. Beam intensity started increasing again - not sure whats happenig at present (see image 23). </p>
<p>20:26</p>
<p>Around 19:50 beam decreased again and stayed down for a while. Beam not stable. Gleb was called, target turned off, beam restabilied - around 2.5e7 ish. Unsure if it will remain stable during the night (image 24).</p>
<p>20:35</p>
<p>detectors moved back in. Target back in, stable at 4e11.</p>
<p>Potentiometer Left: 36.54 mm</p>
<p>Potentiometer Right: 70.49 mm</p>
<p>Beam stable at the moment (image 25).</p>

<p>System checks 20:40</p>

FPGA Timestamp error counter test result: Passed 6, Failed 10<br />
If any of these counts are reported as in error<br />
The ASIC readout system has detected a timeslip.<br />
That is the timestamp read from the time FIFO is not younger than the last</p>
<p>System wide checks ok except the FPGA timestamps - see error above - collected them and it went away. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly for now.</p>

<p>FEE temperatures OK</p>
<p>System wide checks OK</p>
<p>Statistics and spectrum browser rate look OK</p>
<p>Merger and tape server OK</p>
<p>Monitoring code rates are consistent with beam on target</p>
<p>X2go seems to not be loading full screen for me - may be my laptop misbehaving?</p>
<p>Can see ring intensity has been stable for the last hour, target density is 4.33e11 and YR09 pressure is 1-2e-10 mbar.</p>
<p> </p>
<p>23:22</p>
<p>Target density 4.3e11, beam intensity stable.</p>
<p>Monitoring code rates are consistent with beam on target</p>
<p>Fee temps all OK</p>
