02:02 Recovered DAQ from crash. Merger became clogged and the system required a full restart. Raspberry pi also required a restart to regain control of the USB power relay. AIDA R16 started BigRips on run 0143 which started at 01:19 BRIKEN run 2 Biases and leakage currents ok see attachment 1 Screenshots attached for good events, sync, pause and resume (attachments 2-5) 02:23 BigRips started run 0144 AIDA on run R16_5 BRIKEN run 3 02:47 All system wide checks ok 03:25 BigRips Run 0145 AIDA run R16_22 begins at 03:26 BRIKEN run 4 All system wide checks ok 04:00 Biases and leakage currents ok (attachment 6) 04:25 BigRips has stopped. AIDA run R16_37 brief stop in beam time as Shunji got access to the area and removed the fixed degrader. In the hope that we were stopping ions before they reached AIDA. It is now attached to the furthest upstream variable degrader. 04:29 bigRips run 0146 AIDA run R16_38 BRIKEN run 5 System wide checks ok, ASICS settings checked 05:31 BigRips beam stopped. Carbon foil change AIDA file run R16_54 BRIKEN also stopped Was running with 13mm of Al. Switching to 11mm of Al degrader. 05:41 BigRips start Run 0147 AIDA file R16_57 starts at 05:52 BRIKEN run 6 System wide checks all ok. 06:00 Bias and leakages ok (see attachment 7) 06:26 System wide checks ok 06:43 BigRips stopped their run. AIDA currently on R16_73. Still running even after LN2 fill. 07:17 BigRips start run 0148 AIDA run R16_81 BRIKEN run 7 System wide checks and ASIC load all ok 07:42 Bias and leakage currents ok (see attachment 8) 08:22 System wide checks all ok 08:36 BigRips started run 0149 AIDA file R16_104 08:41 BRIKEN run 8 09.30 System-wide checks all ok. Leakage currents ok (see attachment 10). 09.43 BigRIPS run 0150 starts. Corresponds to the beginning of R16_125. 10.35 System-wide checks all ok. nnaida1 still fails clock status check, but bit 2 is set. Leakage currents ok. R16_141. 10.44 BigRIPS run 0151 starts. Corresponds to the end of R16_142. 11.40 System-wide checks all ok. nnaida1 still fails clock status check, but bit 2 is set. Leakage currents ok. R16_141. 11.45 BigRIPS run 0152 starts. Corresponds to end of R16_159 12.00 Leakage currents all ok (see attachment 11). 12.47 PE16/R16_178 BRIKEN file 11 BigRIPS run0153 12.50 System wide checks OK except nnaida1 fails global clocks 6 ASIC check control 13.41 1.8.H and 1.8.W spectra 13.43 System wide checks OK except nnaida1 fails global clocks 6 14.03 BigRIPS run 0154. Roughly start of R16_199. 14.21 BigRIPS run 0155. Start of R16_204. 14.50 System-wide checks all passed except nnaida1 fails global clocks 6. Leakage currents ok. 15.23 Beam off. ~Half way through R16_220. Degrader reduced from 11mm to 8mm. Previously no pulser visible in p-side FEEs. Jiggled pulser cabling and pushed all LEMO connectors in. Pulser no visible in 1.8.L for all p-side FEEs. 15.28 Beam returned. End of R16_221. BigRIPS file 0156. 15:40 STQ problem so beam stopped near start of R16_225. 16.05 Beam returned to F11. 1.7G into R16_231. BigRIPS file 0157 BRIKEN file 15 System-wide checks all passed except nnaida1 fails global clocks 6. Leakage currents ok. 17.20 BigRIPS file run0158 17.38 Bias & leakage currents OK - see attachments 16-17 FEE64 temperatures OK - see attachment 18 Statistics - good events, AIDA disc, SYNC, PAUSE, RESUME, correlation L - see attachments 19-24 Merge statistics - see attachments 25-26 17.40 System wide checks OK except nnaida1 fails global clocks 6 18.21 BigRIPS run0159 AIDA R16_269 BRIKEN file 17 18.44 System wide checks OK except nnaida1 fails global clocks 6 19.31 BigRIPS run0160 AIDA R16_288 BRIKEN file 18 19.55 System wide checks OK except nnaida1 fails global clocks 6 20.22 BigRIPS run0161 AIDA R16_300 BRIKEN file 19 Degrader 8mm Al (unchanged) 21.32 BigRIPS run0162 AIDA R16_318 BRIKEN file 20 Degrader 8mm Al (unchanged) 21.32 Bias & leakage currents OK - see attachments 27-28 FEE64 temperatures OK - see attachment 29 21.38 System wide checks OK except nnaida1 fails global clocks 6 22.16 BigRIPS run0163 AIDA R16_329 Degrader 8mm Al (unchanged) 22.30 System wide checks OK except nnaida1 fails global clocks 6 22.33 AIDA synchronised - R16_333 - see attachment 30 23.07 BigRIPS run0163 AIDA R16_341 BRIKEN Degrader 8mm Al (unchanged) 23.28 ASIC settings 2017Mar27-16.12.39 BNC PB-4 Amplitude 90,000 x5 attenuator IN t_r 50ns tau_d 50us frequency 25Hz range polarity- tail pulse, delay MIN 23.35 System wide checks OK except nnaida1 fails global clocks 6 23.28 Analysis of data fileR16_347 - see attachment 31 23.48 daid on shift.
