(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.

Temps OK - attach

Stats OK - attach

All checks OK

Leakage OK - attach

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
