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.

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.

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.
