beam is back
16:45
  57   Thu May 16 18:28:31 2024 Ide, HubbardRunsNo beam to ESR
beam issues between 18:23-18:26
and beam completely lost from 18:27 till 18:32
in the SIS an issue with a dipole occured

  58   Thu May 16 18:33:30 2024 Ide, HubbardRunsBeam returned to ESR
Beam is back at 18:32 
now in the particle plot the peaks seem to be more isolated than before (see attachment 1)
since 18:36 it looks like before (see attachment 2)

  60   Thu May 16 19:10:27 2024 Ide, Hubbard, Xinliang, David, ShahabRunsNew Run setting for Zr Isomer hunt
19:10 runs from now on run with an optimized setting:

we did a lot of optimization for the hunt of Zr isomer:

1- increased the time as much as possible, but stay within the 1:1 cycle with FRS
2- increased the sampling rate from 6.25 MSPS to 50 MSPS (!) going down to very short recording times --> 300ms only

We are now taking data with this settings for about half an hour.
  61   Thu May 16 21:13:18 2024 Ide, HubbardRunsIntensity drop
The intensity dropped at 21:10 from ~ 1.6E9 down to ~ 8E8

  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

  71   Fri May 17 17:08:24 2024 Jelena B, Zsolt P.RunsNew setting from 5p.m.
NEW SETTING 

All runs from 17:00 are with new setting, due to changing the directory - transfer from old to new one around 200 runs.
  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.
  86   Sat May 18 00:37:21 2024 Helmut, Wolfram, Shahab, David, XinliangRunsTrying to get back to Zr setting
  87   Sat May 18 00:37:52 2024 Helmut, Wolfram, Shahab, David, XinliangRunsSIS beam gone
