<p>18:05 We believe we have an overlap between the beam and the target. Run 22 started.</p> <p> CARME detectors in with the servo ONLY. Left arm pot 36.5 mm, right arm pot 37.7 mm</p> <p> Target density apporx 2e11 atoms/cm2.</p> <p> Shots into the rin partially stable (sometimes consecutive injections at high intensity, sometime apporx 1 in 4 fail rate).</p> <p> We plan beam run overnight, remote shifters will check on the progress every 2 hours.</p> <p>18:32</p> <p>Everything ok.

Spectrum borwser shows this is from a single strip. Checl load aida09 several times but no change to the rate.</p> <p>Leakage current appears fine. (Attachment 23)</p> <p>Merger and tape server OK</p> <p>Ring pressure appeared to have dropped and the target density had dropped to approx 5e10 at/cm2 range. Target nozzle moved 200 steps. Density back to 2.5e11 range and pressure is high -11 low -10 mbar range. <----- Operator mistake</p> <p>XY plot all detector (attachment 24)</p> <p>EyTotal all detectors (attachment 25)</p> <p> </p> <p>05:08</p> <p>Target density appears to have been very stable over the last few hours ~2e11 at/cm2. Ring pressure also appears stable.</p> <p>FEE temperatures OK</p> <p>System checks OK</p> <p>ADC data items appears ok for all FEEs,Aida09 rate appears to be reduced again.</p> <p>Leakage current appears fine.</p> <p>Spectrum browser rates (attachment 26)</p> <p>Spectrum browser stats (attachment 27)</p> <p>Spectrum browser 1.8*L pn (attachment 28)</p> <p>Spectrum browser 1.8*L nn (attachment 29)</p> <p>New merger stats (attachment 30)</p> <p>I am not confident we are seeing significant Rutherford scattering accumalated so far.</p> <p> </p> <p>07:18</p> <p>FEE temperatures OK</p> <p>System checks OK</p> <p>Stats OK</p> <p>Leakage current appears fine.</p> <p>Spectrum browser rates OK</p> <p>Spectrum browser stats OK</p> <p>Spectrum browser 1.8*L OK</p> <p>Spectrum browser 1.8*L nn OK</p> <p>New merger stats OK</p> <p> </p> <p>7:40</p> <p>Noticed operator mistake at 3 am. Ring pressure was very bad in YR08. Unlikely we had much beam since then. Moved nozzle to improve pressure.</p> <p>See attach 38 & 39.</p> <p>08:51</p> <p>Checks all ok.
