> 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.
