<p>02.08 Tried updating AIDA SYNC on stats page and got this message.</p> <p> See attachment 8</p> <p> </p> <p>02.16 Runs R1201-1206 are short runs on the 1GeV, each wit the variable degrader thickness changed to alter the depth of implantation (estimated by visual scalar rates per DSSD)</p> <p> Started 02.16 - 02.47</p> <p> </p> <p>02.56 Started R1207 (EURICA run_1407, BigRIPS run 1192).</p> <p> Settings file 2016Jun07-05.50.53. All nnaida back to 20MeV setting.</p> <p> Temps ok. Leakage currents ok.</p> <p> 3.68mm variable degrader in + 19.3mm fixed degrader.</p> <p> Operator stopped beam @ 03.41. Run stopped.</p> <p> Merger outputting some info to terminal re. unexpected header found (attachment 3)</p> <p> </p> <p>04:05 Beam is back, but some trouble to get AIDA DAQ happy</p> <p>04:52 Started R1208 (EURICA run_1408, BigRIPS 1193)</p> <p> Settings file 2016June07-02.50.53</p> <p> From 5:05 to 5:20, F82a, and F51a (twice) trip. We reduced the F51a from -745 V; -735 V; to -720 V settings.</p> <p> </p> <p> 06:51 Continued with R1208_19 (EURICA has 1410 begin at 6:40, BigRIPS began 1195 at ~7:00)</p> <p> Biases uploaded as attachments 4 and 5</p> <p> 7:13 data stopped going to disk</p> <p> Shortly after that (7:15) operator calls to take control of the beam.</p> <p> </p> <p>07.40 Beam returned. Some trouble restarting DAQ.</p> <p> </p> <p>07.56 Run R1209 started.</p> <p> Settings file 2016Jun07-02.50.53</p> <p> No changes to settings or degraders. Temps ok.
