02.08 Tried updating AIDA SYNC on stats page and got this message.
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; See attachment 8
&nbsp;
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)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Started 02.16 - 02.47
&nbsp;
02.56 Started R1207 (EURICA run_1407, BigRIPS run 1192).
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings file 2016Jun07-05.50.53. All nnaida back to 20MeV setting.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Temps ok. Leakage currents ok.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.68mm variable degrader in + 19.3mm fixed degrader.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Operator stopped beam @ 03.41. Run stopped.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Merger outputting some info to terminal re. unexpected header found (attachment 3)
&nbsp;
04:05 Beam is back, but some trouble to get AIDA DAQ happy
04:52 Started R1208 (EURICA run_1408, BigRIPS 1193)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings file 2016June07-02.50.53
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; From 5:05 to 5:20, F82a, and F51a (twice) trip.&nbsp; We reduced the F51a from -745 V; -735 V; to -720 V settings.
&nbsp;
&nbsp;06:51 Continued with R1208_19 (EURICA has 1410 begin at 6:40, BigRIPS began 1195 at ~7:00)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Biases uploaded as attachments 4 and 5
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 7:13 data stopped going to disk
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Shortly after that (7:15) operator calls to take control of the beam.
&nbsp;
07.40 Beam returned. Some trouble restarting DAQ.
&nbsp;
07.56 Run R1209 started.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Settings file 2016Jun07-02.50.53
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; No changes to settings or degraders. Temps ok. Leakage currents ok.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PPACs tripped repeatedly around 08.10.
09.13 Beam setting changed and run stopped.
&nbsp;
11.25 Current status
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Julabo FL11006 recirculating chiller set point +15.0deg C (B3F +24.6 deg C, dew point +10.3 deg C, RH 40.7%)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; System-wide checks - all FEE64s pass all tests *except* nnaida19 which fails ASIC clock timestamp and SYNC errors not counting
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i.e. status is unchanged
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; nnaida19 merge data link (#18) disabled - see attachment 12
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; nnaida19 ReSYNCs OK but timestamp is adrift of other FEE64s - see attachment 11
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Detector biases &amp; leakage currents - OK - see attachments 9-10
