 Thu May 16 16:38:11 2024, Ide, Hubbard, Runs, No beam to ESR
|
because of problems in HHT
no beam from 16:36 |
Thu May 16 16:10:03 2024, Ide, Hubbard, Runs, Lassie Screenshot 
|
Lassie Screenshot taken at 16:09 |
|
Thu May 16 15:24:30 2024, Ide, Hubbard, Accelerator, new Plunger setting
|
plunger motors were set
to +/-390 mm for 245 MHz resonator
and +/-55 mm for 410 MHz resonator |
|
Thu May 16 14:52:45 2024, Shahab, DAQ, Zr recording
|
Recording Zr starting from 14:45 again back to short cycle. |
|
Thu May 16 13:04:02 2024, Mayr, Hannes, Runs, DAQ stopped, change setting to 98Zr
|
Beam tuning for 98Zr starting at 12:53, following data should be excluded from analysis. DAQ was stopped around 13:13. |
|
Thu May 16 12:48:58 2024, Sergey, Accelerator, Tune to 98Zr
|
- stop longer measurements
- change quadrupole and sextupole magnets
- rescale SIS-TE-ESR |

Thu May 16 11:13:05 2024, Mayr, Hannes, Runs, Rates
|
With the new timing, the rates now look like can be seen in the screenshot. |
|
Thu May 16 11:08:27 2024, Mayr, Hannes, Runs, DAQ running again
|
"Real" measurement with good data starting from 11:07 until approximately 13:00.
Measurement time was changed to 10s with injections every 32s. |
|
Thu May 16 10:18:14 2024, Mayr, Hannes, Runs, Beam back, DAQ off
|
Beam is back since 10:10, but DAQ is turned off to change the setting there.
Measurements starting at 10:18 are only test runs and should not be used for analysis. |
|
Thu May 16 09:41:56 2024, Mayr, Hannes, Runs, No beam
|
No beam from 09:39 to 10:10 due to a setting change. The change aims to increase the measurement time to 10s. |
|
Thu May 16 08:58:39 2024, Mayr, Hannes, Runs, Fluctuations in particle rate
|
Particle rates are fluctuating and increasing from a constant 5e8 to something around 1e9. |
|
Thu May 16 07:50:39 2024, Mayr, Hannes, Runs, Peaks with very high particle rate
|
Peaks in the particle diagram going to unusual high 1.4e9 particles. |
|
Thu May 16 07:25:33 2024, Mayr, Hannes, Runs, Lassie Screenshot 07:23
|
Start of regular screenshots of the Lassie monitor every 1-2 hours. |
|
Thu May 16 04:37:27 2024, Boguslaw, Camille, Runs, No beam to ESR
|
We had no beam in ESR for about 3 minutes |
|
Thu May 16 00:37:41 2024, Boguslaw, Camille, Runs, Injection pattern changed
|
The injection pattern changed on Lassie monitor (0:27 AM). (picture 1)
It when back to the previous rate at 1:48 AM. (picture 2)
The same pattern change appeared from 3:01 AM to 3:07 AM. (picture 3) and from 3:24 AM to 3:39 AM. |

Wed May 15 23:04:32 2024, Xinliang, Analysis, Electron cooler data
|
The cooler curve measured during May 14 afternoon. |
|
Wed May 15 20:40:51 2024, Jeroen, Johan, Runs, Beam returned to ESR
|
20:39:42 Runs restarted. |
|
Wed May 15 20:17:20 2024, Jeroen, Accelerator, Fewer spills from SIS18 then lost beam
|
Apparently fewer spills coming from SIS18, see attached.
Beam was lost at 20:17:52. |
|
Wed May 15 19:45:44 2024, Helmut Weick, Accelerator, Cooler curves after beam shift
|
After the Beam position tuning but before the scraper tuning two more cooler curves were taken.
The first with all scrapers open shows a similar shape to before with the same quadrupole setting.
Afterwards the ESR ebergy was shifted by -0.8 MeV/u to get the beam more on an outer orbit.
The curve then is shifted and has a bit less acceptance. |
