(ignore 26 - in-between run)
We start a new run with real data taking condititon: beam is ok, target density is 9.6e11 cm-2, detectors are moving in-out periodically.
Cooler voltage setpoint 1128 V.
Beam energy = 1.99 MeV/u (from HKR) (same as run 25)
Left arm at 18.86 mm
Right arm IN at 83.69 mm (OUT 37.96 mm)
vertical beam position 0.0 mm
horizontal beam position -3.5mm
Beam intensity ~1e+7 particles.
Target density ~9.6e11 at/cm2
Target temperatures: T1=31.5 K T2=35.2 K
Beam cycle set to 10 seconds.
11;57
All checks OK.
Aida10's rates seems low now, but aida07 is instead jumping between 200 and 4000 following beam.
15:45
Root histograms refreshed.

Base Current Difference
aida01 fault 0x0 : 0x1 : 1
FPGA Timestamp error counter test result: Passed 15, Failed 1
If any of these counts are reported as in error
The ASIC readout system has detected a timeslip.
That is the timestamp read from the time FIFO is not younger than the last
