  17   Wed May 15 01:11:45 2024 David, Asahi, Shahab, Chris, RuijiuGeneralTime optimisation
DAQ stopped at 01:11 to optimise data taking cycle of RSAs. 
Changed data writing time from 2s -> 1.8s.
  19   Wed May 15 02:07:02 2024 Chris G, Asahi YGeneralNo beam to ESR
Injection to ESR stopped around 02:04:45.

Will continue to write data in hope that beam returns shortly.
  20   Wed May 15 02:12:59 2024 Chris G, Asahi YGeneralBeam returned to ESR
Injection to ESR restarted around 02:12:15
  22   Wed May 15 09:35:08 2024 Beatriz, MinGeneralNo beam
At 9:32 we lost the beam. They have to work in the Unilac and there will be no beam for 45 minutes. 
  23   Wed May 15 10:58:32 2024 Beatriz, MinGeneralBeam returned to ESR
Beam recovery at around 10:52:30. Sergey and Yuri still tuning the mass resolution.
  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.
  28   Wed May 15 16:55:10 2024 Jeroen, JohanGeneralTuning ESR scraper. Isomer resolved.
4:50 Scraper tuned to produce Gaussian beam profile for 98Mo. Isomer now clearly resolved.

Plan to take data for 98Mo fragment for 12 hours. Measurements from 4:59 are now aligned so that the Molybdenum fragment is centered in the RSA acquisition.
  30   Wed May 15 17:45:09 2024 Jeroen, JohanGeneralNo beam to ESR
Beam lost from SIS18 at 17:41:41.
  31   Wed May 15 17:47:34 2024 Jeroen, Johan, ShahabGeneralNew Trigger Setup
We changed the trigger setup, see attachment
  59   Thu May 16 18:55:38 2024 Ide, HubbardGeneralnew timing cycle
new timing cycle of 6.7s
  68   Fri May 17 16:34:43 2024 Jelena B, Zsolt P.GeneralBeam issues
We lost beam at 16:29. 
Cooler has to be investigated. 
  69   Fri May 17 16:42:00 2024 Jelena B, Zsolt P.GeneralBeam back
Beam is back at 16:38.

We are changing the setting.
  75   Fri May 17 20:33:43 2024 Jelena B, Zsolt P.GeneralBeam returned to FRS
We have again beam at FRS..
But we are taking still cycles on a same way as before...and discussing to go back to the old zirconium setting 

In one hour HHT will enter the cave. 
  76   Fri May 17 21:44:39 2024 Jelena B, Zsolt P.GeneralBeam issues
We do not have beam, and we have some instability during last 1-1.5 hour. 
  82   Fri May 17 23:14:51 2024 Yoshi, OhnishiGeneralshift started
Just test
  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.
  85   Sat May 18 00:15:44 2024 Yoshi, OhnishiGeneralBeam back
Beam is back, but it stopped again at 0:17......
  107   Mon May 20 09:01:51 2024 Oliver, JelenaGeneralShift news
Data collection runs smooth so far.

Yuri Litvinov will start modifying SP magnets now. The resolution will change.
  108   Mon May 20 13:26:55 2024 Jelena, Oliver, ShahabGeneralPlunger values
plunger 150 for 250
plunger 48 for 410 
  109   Mon May 20 13:31:09 2024 Jelena, Oliver, ShahabGeneralNew setting focussing on 96-Sr
plunger 150 for 250
plunger 48 for 410 

From file starting from 13:21 is a new setting for 96Sr.
