Run 33 started cooled beam on target.

Detectors IN (left arm pot =36.5 mm, right arm pot = 70.49 mm)

Electron cooler voltage 754.945 this corresponds to 1.3499 MeV/u. This is above the resonance of interest but cooler settings cannot be altered without major beam tuning.

Target density is 4.1e11 at/cm2, ring pressure looks OK YR09 1.2e-10 mbar.

Horizontal beam position is -7.5 mm, vertical beam position is now 0.0 mm. This results in no beam halo in bottom left detector which should be good for seeing Rutherford.

Beam is in the ring for 8 seconds and total cycle time between injections is 12 seconds

FEE temperatures are OK. 3 FEEs are slightly too. (attachment 1)

System checks are OK.

Statistics look OK. High in the top left detector which is expected as majority of halo is there. (attachment 2+3)

Merger OK Tape server OK - 851 kB/s

Merger statistics (attachment 4)

Leakage current is increasing but is likely temperature related. ML temp plot has same pattern and it is a WARM day. (attachment 5)

Monitoring code - xy plot and Ey energy histograms (attachment 6+7). Rutherford rate looks higher -> looking peaky

00:14

System checks all OK

FEE temperatures unchanged. Tom has now set up plotting of aida09 fee temperatures in the second workspace.

Merger OK, tape server OK.

Target density remains about 4.1e11 at/cm2. Ring pressure ~1e-10 mbar. YR08 read close to 1e-9 but beam is able to circulate in the ring so will not change for now.

Rate statistics in all FEEs remain unchanged.

02:10

System checks OK

FEE temperatures unchanged

Merger OK

Target density OK. Ring pressure not great but cannot change remotely due to script not in screen and poor coding.

Beam stil on.

Leakage current trending up.

04.00 FEE64 temperatures - attachments 10-11

          aida09 ( and other FEE64s ) on downward trend

          CRYRING hall temperature - attachment 12

05:00

Ring pressure worsening and target getting thinner (4E11). Tweak nozzle when in the lab physically.

Beam still on around 3E7

Temperatures & Leakage currents OK. Same trends

Merger continues OK

Stats OK

System wide checks OK

07:00

Fee temperatures have reduced - all green

System check OK

ADC data items statistics unchanged. 

Merger and tape server OK

Leakage current plot (attachment 15)
monitoring  plots - xy plot and EY energy histogram (attachment 16+17 )

Pressure has dropped slightly over the last hour, target density remains stable 4.2e11. Beam transformer has dropped off in the last hour -> less beam target interactions -> lower pressure?

We still see count rates in the detectors.

08:18

Inconsistent beam into the ring continues. HKR are aware.

Temperatures OK

System checks OK

10:00

Beam is much more consistent now. We observe vast majority of shots injected into the ring and corresponding rate increase in the detectors via the monitoring code.

FEE temperatures OK

System wide checks OK

Merger and tape server OK

New merger stats (attachment 18)

ADC data item statistics OK

Leakage current plot (attachment 19)

Attachments 20+21: Cooler settings before and after changing to the new beam energy of 1.3435 MeV/u (copy from GSI olog)

10:24

Run33 stopped. Run 34 started. Changing beam energy to be on resonance.

Detectors moved fully out. Target moved out
