Sun Jun 2 13:04:41 2024, JM, AG, CB, DR, Run 23 - vertical beam position and beam lifetime tests
|
14:05
Run 22 stopped. Run 23 started we will now adjust the vertical beam position to see if we observe the beam stripe seen in the last beamtime.
Current vertical beam position 0.0 mm. Horizontal beam position 7.0 mm. Coasting beam. |

200x cycles |
|
Sun Jun 2 06:41:00 2024, CB, AG, Run 21 - tests 10x
|
07:41
Switching to bunched beam to check D vs H content.

Sat Jun 1 07:16:15 2024, CB, AB, EM, JM, Run 19 - beam target overlap 19x
|
Morning shift
08:16 - as run 18, target off
9:00 Increased storage time to 5 minutes. Aquired data after initial beam loss. Attach 1 &2. Far less H2+ vs D. |
|
Fri May 31 21:53:20 2024, CB EM, JM,EM AB, Overnight beam tests 17x
|
22:53
Run 15 started
Beam tests. We increased the storage time to 2min and switched to bunched beam so that we can see the beam lifetime over the cycle. |
|
Fri May 31 21:03:21 2024, CB, EM, Run14
|
22:03
Before this run we checked quickly beam with the target on but it does not make sense with the current status of the beam.
We removed target and starte Run14 |
|
Fri May 31 19:12:01 2024, CB, EM, Run 13 - test with beam
|
20:00
The beam is set at the correct energy, operators cross-checked it again. What we see at 750 is due to the molecular beam. The operotors
are trying to optimize and get rid of this in the next 30min. |
|
Fri May 31 06:01:55 2024, JM, TY, PW, EM, CB, Run 12 - beam on target 12x
|
07:00
Run 12 started. D+ beam is incident on the target at 1.5 MeV
Beam intensity in the ring is ~4e7 particles |
|
Thu May 30 13:31:01 2024, JM, CB, PW, YL, Run 11 - beam on target overlap
|
14:30
Run 11 started. D+ beam in the ring at 1.5 MeV.
No target at the moment. Valves to the interaction chamber will soon be opened. |
|

|
10:30
Merger OK, Tape server OK
ADC data item statistics looks as before. OK |
|
Thu May 30 08:33:21 2024, CB, PW, YL, Run 8 & 9- detector motion tests 7x
|
09:34 - Moved to Run 9 in preparation of moving detectors. No target yet. Beam in the ring at 750 keV/A.
Temperatures OK (attach)
System wide checks OK except 16 fails clock and ADC calib |
|
Thu May 30 07:25:53 2024, Yuri, Phil, Nikos, Gas target
|
The cave is closed and beam is back
The d intensity is about half of the intensity before the break
The gas target is prepared but the valvas cannot be opened. Anton is coming in at around 1 PM to open the gate valves. |
|
Thu May 30 06:00:51 2024, Yuri Nikos ..., Open the cave
|
Nikos needs to enter the cave to work on the target cooling.
