timeline of run 116

00:xx resync Agata #13C
00:57 lost beam, back at full intensity at 01:12
01:30 lost beam, back at full intensity at 01:45
01:37 FP_CATS5 tripped, reset
01:43 resync Agata #13C
02:04 resync Agata #13C
02:20 lost beam, back at full intensity at 02:30
02:36 resync Agata #13C
03:45 Vamos rate down to 900 pps, checked that intensity on profiler is 1.1e7 so decided to continue
05:58 resync Agata #13C
06:55 Vamos rate at 1400 pps but diamond is decreasing since several hours: we had 17500 counts at midnight and now only 7500.
Checked beam rate on profiler and found 1.8e7 so indeed it is the diamond efficiency that is going down steeply
