  61   Thu May 16 21:13:18 2024 Ide, HubbardRunsIntensity drop
The intensity dropped at 21:10 from ~ 1.6E9 down to ~ 8E8
  63   Thu May 16 21:40:20 2024 Ide, HubbardRunsIntensity drop
Intensity in particles dropped from 21:33
  62   Thu May 16 21:26:50 2024 Ide, HubbardRunsIntensity back to previous values
since 21:20 the intensity is back to 1.5E9
  64   Thu May 16 21:51:22 2024 Ide, HubbardRunsIntensity back to previous values
since 21:48 particle intensities increased to again to 1.5E9
  39   Thu May 16 00:37:41 2024 Boguslaw, CamilleRunsInjection 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.
  6   Sun May 12 18:34:54 2024 RuijiuAnalysisHow 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.
  84   Sat May 18 00:06:56 2024 ShahabRunsHHT people out again
we try to re run the ESR. ESR behaves very strangely. Something not so right.
  83   Fri May 17 23:30:16 2024 ShahabGeneralHHT people inside
no beam since about one hour, also HHT people inside since about 10 min.
  55   Thu May 16 16:43:29 2024 YuriAcceleratorHHT
HHT sees radiation from us. We stop for 10 min for them to see the speed with which the radiation level decreases.

  43   Thu May 16 08:58:39 2024 Mayr, HannesRunsFluctuations in particle rate
Particle rates are fluctuating and increasing from a constant 5e8 to something around 1e9.
  16   Wed May 15 00:26:53 2024 David, Asahi, Shahab, Chris, RuijiuRunsFirst data file - 00:26
Centered resonant frequency on 98Mo+42 at the 126 harmonic (243.925 MHz) and 211 harmonic (408.483 MHz).
Recording for 2 seconds (injection start at 10%), injection every 6 seconds. 
  25   Wed May 15 11:59:32 2024 Beatriz, MinDAQFile transfer to lustre looks to be stopped
File transfer to lustre looks to be stopped at around 11:35AM
  35   Wed May 15 20:17:20 2024 JeroenAcceleratorFewer spills from SIS18 then lost beam
Apparently fewer spills coming from SIS18, see attached.

Beam was lost at 20:17:52. 
  113   Tue May 21 08:50:06 2024 YuriAcceleratorEoB
End of beamtime!
Request is out.
Scrapers are removed, slits in the TE line removed, ESR is ramped down.
  38   Wed May 15 23:04:32 2024 XinliangAnalysisElectron cooler data
The cooler curve measured during May 14 afternoon.
  80   Fri May 17 22:43:11 2024 Jelena B, Zsolt P.AcceleratorESR_e.cooler are back
We have back ESR and we have a fixed issue with a cooler. 

Beam issues! 
  27   Wed May 15 13:39:10 2024 Beatriz, MinGeneralESR 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.
  Draft   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.
