  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.

  40   Thu May 16 04:37:27 2024 Boguslaw, CamilleRunsNo beam to ESR
We had no beam in ESR for about 3 minutes

  26   Wed May 15 12:58:12 2024 Beatriz, Min, ShahabRunsoptimizing the mass resolution
Yuri and Sergey still optimizing the mass resolution.

From 13:10 to ~ 13:35 SIS energy was increased to 457.4 (~3 MeV/u) to test whether this moves the best isochronicity to 98Mo (we were off before), -> Brho(98Mo)=7.12736 Tm

From ~13:35 back to setting up with the primary beam at 441.95 MeV (with target, same Brho as the 98Mo fragments). It will be attempted to measure the orbit of the beam
  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.
  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
  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.
  66   Fri May 17 00:15:24 2024 Ahmed, Zidarova, KalaidjievaRunsBeam gone
HHT called and said they have problems and need to enter the cave, so they stop the beam for some time
Beam Stop 00:10
Beam back 01:01

HHT have more problems and need to enter the cave, beam is stopped for some time
Beam stop: 05:46

for checking Markus hypothesis about the longevity of the bunched beam due to the ISO mode. This is important to understand lifetime measurements in ISO mode, otherwise the information might be affected.
