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

|
Thu May 16 16:43:29 2024, Yuri, Accelerator, HHT
|
| HHT sees radiation from us. We stop for 10 min for them to see the speed with which the radiation level decreases. |
|
Sat May 18 14:43:59 2024, Yuri, Accelerator, Reduce intensity, 98Mo42+
|
reduce intensity
eexds2ha 7mm --> 9 mm
e02ds3hg -69 mm -- stays

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.

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 11:09:15 2024, Yuri, General, Logbook for beam tuning.

|
| Beam is back, but it stopped again at 0:17...... |

|
| RSA01 was stopped from 19:25, it restart now. |

|
| The beam is paused and HHT team needs to enter the ring. |

Wed May 15 23:04:32 2024, Xinliang, Analysis, Electron cooler data
|
| The cooler curve measured during May 14 afternoon. |
|
Sat May 18 01:57:44 2024, Weick, Accelerator, 96Sr isoc setting
|
We fist verified the ESR after a crash with the 98Zr setting, was fine good resolution,
then we scaled to 96Sr directly at gamma_t not with shift as before.
E_SIS = 449.21 MeV/u for 100Mo 38+

|
| 15:20 RSA DAQ stop -> Sr setting |
