00:11 BigRIPS has started a new run at 00:10:42 run 0165. AIDA subrun R16_357 was about halfway (~1 GB) at 00:11. BRIKEN run 21 ( so-called 170331_0012_Mg40 ) Check clock status: FEE64 module nnaida1 global clocks failed, 6 [ as usual, and it is set to ch 2 ] ADC calib all pass Clock timestamp, passed Sync counter error, passed Sync pulses all consistently near 3 x 10^7 Memory info from Linux FEE64 all around 35k to < 40k Sync check on the BRIKEN terminal is looking all consistent to me. Temperatures are seen as attachment 1, temps_31_a.png Biases and leak currents seen as attachment 2, bias_31_a.png As for what I've checked then we continue on in what appears to be a stable condition. 01:12 I can see BigRIPS team at their DAQ PC about to change the run. 2017-03-31 01:12:24 BigRIPS run 0166 starts AIDA subrun R16_372 is 75% finished at 1:12 BRIKEN run 22, [ 170331_0114_Mg40 ] -- timestamp beginning at 1:14 means they are almost exactly at the beginning of AIDA R16_373 Check clock status, ibid to above Check ADC calib, ibid Check ASIC clock timestamp, ibid Check sync errors, ibid Check sync pulses, 3.2 x 10^7 consistently Check FEE64 memory, 36k to 37k. Sync check at BRIKEN is still running and shows the clocks are lined up. Continue. 02:10 BigRIPS begins a new run, number 0167 AIDA subrun R16_386 finished at 2:10, so BigRIPS 0167 should correspond nicely with the start of AIDA R16_387 BRIKEN run number 23 [ 170331_0214_Mg40 ] All six (6) system wide checks were performed. The situation remains stable as above. 03:13 BigRIPS starts a new run at 3:12:51 AIDA R16_402 is about 50% complete at 3:13 BRIKEN 24 [ 170331_0314_Mg40 ] All system-wide checks are passed. Number of sync pulses is ~3.7 x 10^7 03:33 Bored so here's some spectra, attachment 3 as pulses_31_b.png. It looks good. 04:10 BigRIPS run 0169 began at 2017-03-31 04:09:50 AIDA is R16_416 50% though at this time. BRIKEN 25 [ 170331_0413_Mg40 ] All checks passed. I'm not just writing it, but they were performed :) See attachment 4 for bias. had screencapped temp but forgot to update so it was just a clone of attachment 1 (this was noticed at 8:07) 04:58 Beam operators called. They stopped the beam so they can exchange the carbon stripper foil. AIDA R16_428 was 25% through at 4:58. 05:02 R16_429 is at 600 MB I hear the chime to indicate the beam is back BigRIPS 2017-03-31 05:02:57 run 0170 is started BRIKEN run 27 [ 170331_0504_Mg40 ] -- NB: Run 26 was junk (some mistake) All six (6) system wide checks are a go. 3.7 x 10^7 is the sync pulse count. Continue. 05:12 I show you the AIDA look good in attachment 5 spec_31_c.png 06:10 still waiting on BigRIPS to notice what time it is. 06:14 BRIKEN sends the resync. (this note is written at 7:11..see below) 06:16 R16_447 Jorge realizes there are no neutrons in BRIKEN, and we realize the second beam physicist is on the phone. 06:29 Beam physicists hang up the phone...2017-03-31 06:29:30 BigRIPS run 0171 AIDA run R16_451 is almost exactly beginning at 6:29 BRIKEN run number 28 The system wide checks are consistent as before FEE64 module nnaida1 global clocks failed, 6 Check sync pulses sees 3.9 x 10^7 06:36 - I asked the BigRIPS team the situation. Basically, they calibrate the faraday cup and also three plastic scints near F0 (primary target) for calibrartion (cross section estimation) purposes. So it seems in this time THEY have the beam yet we do not because it is not reaching all the way to F11 the entire time. Though I do not want to bother the operators with too many questions, it can be that parts of BigRIPS run 0170 near the end will not correlate with our data. 07:11 - I had not caught that BRIKEN sent the resync. It was confirmed that it was the only resync issued tonight. Please see the attachment 6 "spec_31_d.png", though I'm not sure it would be useful 07:47 Not sure the situation. Beam physicists were near their DAQ PC for a bit, then on the phone, but their run has not restart. AIDA run R16_469 at this time, just to note. 07:57 2017-03-31 07:55:33 BigRIPS run 0177 is started. Evidently run 0176 is skipped somehow. AIDA R16_471 was at 1.9 GB at 7:57 so probably it mostly correlates with the start of the BigRIPS run. BRIKEN run number 29 (?) [ 170331_0758_Mg40 ] [8:15 - confirmed the problem with beam physicists was a DAQ issue. Thus BigRIPS run 0172 is junk, and they took some time to resolve their issue.] System-wide checks look normal. 4 x 10^7 sync pulses Attachments 7 and 8 have bias and temp ("bias_31_e.png" and "temp_31_e.png") 08:07 When doing the temperature this time, I realized that an early temperature "temp_31_b" was just a clone of "temp_31_a" as I forgot to refresh. Now the attachment numbering changes as I delete it, and the elog is updated to correctly reflect the new ordering. I should be more careful. 08:56 BigRiips start run 0174 End of AIDA file R16_485 BRIKEN file 31 System wide checks all ok except nnaida1 fails global clocks 6 ASIC check all ok 09:44 BigRips stopping the beam Half way through AIDA file R16_498 09:57 System wide checks all ok except nnaida1 fails global clocks 6 10:01 BigRips start run 0175 Start of AIDA file R16_502 BRIKEN file 32 10:11 Biases and leakage currents ok (See attachment 9) 10:19 BigRips start run 0176 End of AIDA file R16_506 10:23 BRIKEN start file 33 AIDA on file R16_507 11:21 BigRips start run 0177 End of AIDA file R16_521 BRIKEN start file 34 System wide checks all ok except nnaida1 fails global clocks 6 Temperatures ok (See attachment 10) 12:21 BigRips start run 0178 AIDA file end of R16_536 BRIKEN start run file 35 System wide checks all ok except nnaida1 fails global clocks 6 ASIC load check ok 12:43 Biases and leakages are ok (See attachment 11) 13:20 BigRips run 0179 AIDA halfway through R16_551 BRIKEN start run file 36 System wide checks all ok except nnaida1 fails global clocks 6 13:39 bigRips run 0180 AIDA file end of R16_555 14:44 System wide checks all ok except nnaida1 fails global clocks 6 ASIC load check ok Temperatures all ok (See attachment 12) Biases and leakage currents ok (see attachment 13) 15:14 BigRips is stopped AIDA file R16_579 15:16 BigRips started run 0181 AIDA file end of R16_579 15:24 BRIKEN starts file 37 AIDA file 3/4 of R16_581 16.18 BigRIPS file 0182. Just after start of R16_595. BRIKEN file 38 starts @ 16.21. 16.55 All system-wide checks ok except nnaida1 fails global clocks 6. Temps, bias and leakage currents (see attachment 14) all ok. 17.18 BigRIPS run 0183. ~1/2 way through R16_609. BRIKEN run 39. 18.27 BigRIPS file 0184 started. Start of R16_627. 18.31 Beam stopped at F11 for stripped foil change. Very end of R16_628. 18.38 Beam returned to F11. 1.3GB through R16_630. BigRIPS file 0185. BRIKEN run 40. 19.15 System-wide checks as previously. 19.38 BigRIPS file 0186. End of R16_654 19.43 BRIKEN file 41 started. 20.48 BigRIPS file 0187 started for 30Ne tuning. BRIKEN will not be taking data. 20:50 AIDA stopped on file R16_663 Stopped as end of 39Na and the start of the BigRIPS sweep of settings. 20:52 BigRips starting with 30Ne 20:53 Started AIDA file R17. Centring beam along ZDS. F11 rate ~50cps. All variable degrader in (19mm). 20.58 BigRIPS file 0188 started. 21.04 30Ne setting started. BigRIPS file 0189 started. 21.20 30Ne stopped for 31Ne centring. BigRIPS file 0190. 21.27 BigRIPS file 0191 started for 31Ne yield measurement. (JLT has spoken with operators and it seems up until now beam has been stopped at F7. We are taking this to be the case unless advised otherwise.) 21.59 BigRIPS file 0192 started on 32Ne yield setting. Beam to F11. 22.01 R17 stopped and R18 started. 22.05 32Ne setting finished. R18 stopped. 22.19 BigRIPS file 0194 started for 34Ne setting. AIDA run R19 started. BRIKEN run 43. Currently 10mm degrader but LISE predicts everything should pass through. 22.43 Degrader changed to 19mm Al at start of R19_6. LISE predicts implants in DSSD#2. 23.23 Beam stopped to F11. 1.8 GB into R19_15. 23.25 Beam returned to F11. 1GB into R19_16. BigRIPS file 0195. Degrader reduced to 16.8mm Al.
