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. |

Sun May 12 18:34:54 2024, Ruijiu, Analysis, How to use queqiao to transfer tiq data
|
If the ssh to lxir131 was disconnected, you can connect to lxir131 and restart queqiao program to transfer tiq data from NAS to luster.
1. Open a terminal on any GSI linux computer, like the one in the Measurement Room:
2. start "Online data analysis system":
(base) litv-exp@lxg1478:~$ start_OnlineDataAnalysisSystem
3. click the 3rd button "Copy data from RSA hard disk to luster" to start "queqiao" program.
4. click "start" button on "queqiao" user interface to transfer tiq data on RSA spectrum analyzer.

Sat May 18 00:06:56 2024, Shahab, Runs, HHT people out again
|
we try to re run the ESR. ESR behaves very strangely. Something not so right. |
|
Fri May 17 23:30:16 2024, Shahab, General, HHT people inside
|
no beam since about one hour, also HHT people inside since about 10 min. |
|
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. |

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. |
|
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. |

Wed May 15 23:04:32 2024, Xinliang, Analysis, Electron cooler data
|
The cooler curve measured during May 14 afternoon. |
|
Fri May 17 22:43:11 2024, Jelena B, Zsolt P., Accelerator, ESR_e.cooler are back
|
We have back ESR and we have a fixed issue with a cooler.
Beam issues! |
|
Wed May 15 13:39:10 2024, Beatriz, Min, General, ESR setting
|
From 13:37 ESR will be changed again. Now back to the primary beam, it will be attempted to measure the orbit of the beam. |
|
Fri May 17 22:38:30 2024, Jelena B, Zsolt P., , ESR + e.cooler are back
|
We have back ESR and fixed issue with a cooler. |
