Run 40 started cooled beam on target

Detectors IN (left arm pot =36.5 mm, right arm pot = 70.49 mm). Stationary. Same as run 35

Electron cooler voltage 751.095 this corresponds to 1.338 MeV/u. This should be on the left of the peak of the resonance.

Target density is 4e11 at/cm2, ring pressure looks OK YR09 1.43e-10 mbar.

Horizontal beam position is -7.5 mm, vertical beam position is 0.0 mm. Same as run 35.

Beam is in the ring for 4 seconds and total cycle time between injections is 8 seconds. Notice this is different than run 35.

Statistics, merger statistics, histograms all zero'd

15:39

System wide checks ok. Merger ok. Temperatures ok.

Attatchment 1: statistics

Attatchment 2: Temperatures

Attatchment 3-6: Waveforms. Layout 2 - (attach 4) had a strnageish waveform for aida11, stays after reload.It was the HEC firing so did an ASIC control and Zero'd histograms and all is okay.

Attatchment 7: Leakage current

17:04

System wide checks ok. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly.

Attatchment 8: statistics

Attatchment 9: Temperatures

Attatchment 10-13: Waveforms. Everything looks ok.

Attatchment 14: Leakage current

18:55

System wide checks ok. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly.

Beam transformer shows a small decrease in beam intensity, not drastic but small slow decrease, see attachment 22. Target density 4e11. Vacuum pressue ok.

Run40 - Beam dropped intesntiy at 19:17, moved detectors out, called gleb. Beam intensity started increasing again - not sure whats happenig at present (see image 23). 

20:26

Around 19:50 beam decreased again and stayed down for a while. Beam not stable. Gleb was called, target turned off, beam restabilied - around 2.5e7 ish. Unsure if it will remain stable during the night (image 24).

20:35

detectors moved back in. Target back in, stable at 4e11.

Potentiometer Left: 36.54 mm

Potentiometer Right: 70.49 mm

Beam stable at the moment (image 25).

FPGA Timestamp error counter test result: Passed 6, Failed 10
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

System wide checks ok except the FPGA timestamps - see error above - collected them and it went away. Merger ok. Temperatures ok. The beam is on target and everything runs smoothly for now.

FEE temperatures OK

System wide checks OK

Statistics and spectrum browser rate look OK

Merger and tape server OK

Monitoring code rates are consistent with beam on target

X2go seems to not be loading full screen for me - may be my laptop misbehaving?

Can see ring intensity has been stable for the last hour, target density is 4.33e11 and YR09 pressure is 1-2e-10 mbar.

23:22

Target density 4.3e11, beam intensity stable.

Monitoring code rates are consistent with beam on target

Fee temps all OK

System checks OK

Statistics and FEErates OK.

Merger and tape server OK
