0:04 Biases and leak currents shown as attachment #1, 12JunBias1.png System-wide checks: nnaida13 fails ADC calib, all others okay Temperatures shown as attachment #2, 12JunTemp1.png Implants are 20 to 40 cps, mostly in SSD2 and SSD6 see attachment #3 12JunImplant1.png Statistics shown attachment #4, 12JunStats1.png Analysis shown as R9_175.txt attachment #5 00:17 No implants in AIDA nor proper evt. numbers in BRIKEN R9_177, expect beam is down Operators call, RF dropped of IRC 00:23 Problem of another RF. 00:24 Beam is back R9_179 for AIDA 00:36 AIDA R9_182 at run close. 00:39 AIDA R9_183, BRIKEN 141, run BigRIPS 4031 00:50 We stop the beam to adjust degraders in F11. AIDA R9_186 BRIKEN and BigRIPS runs stopped 00:54 Removed 1.0 mm Al, added 0.5 mm (net is subtracting 0.5 mm Al) R9_187 AIDA run, BRIKEN #142, BigRIPS #4032 01:34 AIDA R9_198 at changeover 01:35 Same AIDA run R9_198, BRIKEN #143, BigRIPS #4033 System wide checks okay (except ADC calib on nnaida13) 02:34 R9_214 at changeover. 2:36 R9_215 with new runs BRIKEN 144 and BigRIPS 4034. More implants are now seen in SSD3 rather than SSD2. Zeroed MIDAS histos, so updated later with stats. Biases as attachment #6, 12JunBiases2.png 02:45 Beam stopped R9_217. Beam stripper has a problem. 02:48 Beam is back, R9_220 03:12 R9_224 operators call, beam is stopped from stripper foil issue 03:18 Beam is back, AIDA run R9_226 03:34 R9_230 at changeover System wide checks all okay, except nnaida13 ADC calib as above. 03:35 The end of R9_230 corresponds with BRIKEN 145 and BigRIPS 4034. 03:51 Operators call, beam looks stopped. R9_235 at AIDA. Change stripper foil 03:57 R9_236 when beam returns. 04:35 We noticed beam is gone. R9_246 for AIDA. 04:36 Beam comes back. R9_247 BRIKEN 146 and BigRIPS 4035 Attachment #7 12JunImplant2.png shows implantation profile, confirming SSD 3 is the main one with new degrader setting Statistics shown as attachment #8, 12JunStats2.png Analysis shown as attachment #9, R9_244.txt No ts timewarps, no MBS timewarps, deadtime on nnaida13,21 nearly 1%, most others small. 05:20 Noticed /data10 only has ~250 GB left, so we should do something to resolve it. First thing is, not much compression is done recently. So I begin to compress /TapeData/RIBF128/R7* with nice 10 However, compression at this rate will take much too long so it looks like something should be removed. Confirmed that RIBF127R1 data file names and sizes are the same between /TapeData and the new external HDD at /ntfs 05:33 AIDA R9_262, BRIKEN 147, BigRIPS 4036 06:34 AIDA R9_279 at run change 06:36 BRIKEN run 148, BigRIPS 4037 System-wide checks passed, except nnaida13 ADC calib still fails. 06:54 R9_284 beam is stopped. 6:59 Beam is back. 07:33 R9_295 at start of BRIKEN 149, BigRIPS 4037 07:36 No syncs are seen at BRIKEN (but they were seen at the start of other runs) Implant profiles shown as Attachment #10, 12JunImplants3.png Several resets or new runs on BRIKEN / BigRIPS are done to troubleshoot 07:48 AIDA passes all system checks (besides the nnaida13 ADC calib) It seems (part of) the issue is triggers from BigRIPS. 08:04 BigRIPS scalers show events are presented, but no triggers are accepted. Some part of the DAQ is vetoing the events basically. 08:11 Baba san came on shift. Issue was ccnet03 crashed. We reset the Camac crate and reinitialized, DAQ comes back AIDA R9_306, BRIKEN #152, BigRIPS # 4041 Encoding: HTML ELCode plain Suppress Email notification
