Tue May 21 08:50:06 2024, Yuri, Accelerator, EoB
|
End of beamtime!
Request is out.
Scrapers are removed, slits in the TE line removed, ESR is ramped down. |
|
Tue May 21 03:27:21 2024, K.Takiura Y.Kikuchi, Runs, Beam back
|
| 03:26 Beam is back. |
|
Tue May 21 03:07:58 2024, K.Takiura Y.Kikuchi, Runs, No beam
|
| 03:07 Beam is down. |
|
Mon May 20 14:02:03 2024, Jelena, Oliver, Shahab, DAQ, Retune 245 MHz
|
| Mew numbers for 245 MHz plunger is 190 (both) |
|
Mon May 20 13:31:09 2024, Jelena, Oliver, Shahab, General, New setting focussing on 96-Sr
|
plunger 150 for 250
plunger 48 for 410
|
|
Mon May 20 13:26:55 2024, Jelena, Oliver, Shahab, General, Plunger values
|
plunger 150 for 250
plunger 48 for 410 |
|
Mon May 20 09:01:51 2024, Oliver, Jelena, General, Shift news
|
Data collection runs smooth so far.
Yuri Litvinov will start modifying SP magnets now. The resolution will change. |
|
Mon May 20 09:01:14 2024, Yuri, Accelerator, Modify SP magnets
|
In attempt to remove double-peak structure, we will modify the SP magnets
START: 9:02
SP unchanged. Other values lead to a worse peak shapes.

Mon May 20 05:32:17 2024, Gregor, Cagla, Accelerator, Short beam interruption
|
| We lost the beam for ~2min at (from ~5:28 till ~5:30). Everything seems to be back at the same state. |
|
Sun May 19 17:48:15 2024, xing xu, hongfu, shahab, Runs, Beam back
|
| beam is back, first file 17:47 |
|
Sun May 19 15:13:48 2024, xing xu, hongfu, Runs, No beam
|
| beam is down 14:45. Problem with UNILAC. may take an hour. |
|
Sun May 19 14:17:57 2024, Shahab, Kanika,hongfu li,xing xu, DAQ, center frequency change for 96Sr
|
aiming for 96-Sr:
|
|
Sun May 19 14:11:29 2024, Yuri, Sergey, Accelerator, Sextupoles
|
at 13:00
scrapers in the ESR are moved to block the most outside orbits
E02DS3HG out -> -60 mm
|
|
Sun May 19 12:04:55 2024, Kanika, Accelerator, Beam back
|
| The beam is back. |
|
Sun May 19 11:02:49 2024, Xu Zhou, Yuhu Zhang, Kanika, Accelerator, the beam is paused
|
| The beam is paused and HHT team needs to enter the ring. |
|
Sat May 18 16:45:15 2024, Helmut, Yury, Accelerator, setting for 96Sr (98Y)
|
To have a few more lines the setting actually is not on 96Sr directly, but on 98Y39+.
98Y is also the one set to be isochronous.
But in addition the SIS-energy is shifted by -0.9 MeV/u to get at least better transmission for 96Sr. |

|
Sat May 18 16:21:30 2024, Taka, Filip, Shahab, DAQ, DAQ start
|
16:21 DAQ restart for 96Sr
Acq. time 300 ms, 50 MS/s, span 25 MHz |
|
Sat May 18 15:26:46 2024, Taka, Filip, DAQ, DAQ stop
|
| 15:20 RSA DAQ stop -> Sr setting |
