Things look ok. No settings have been changed...

Analysis attempts are going on...
  163   Thu Jul 1 00:09:28 2021 David, LilianaGeneralLow beam intensity for few minutes
For few minutes (starting at 00:05) beam intensity went down. Same as it was reported by the previous shift. 
Until 00:27 beam had lower intensity than before (3e8) 
Now intensity is back to 5e8.
  Draft   Sat Jul 3 06:49:55 2021 The remote Canadian eager beavers (Guy &Iris)AnalysisList of possible spectra with isomer decay
Attached is an example for the possible isomer (on the left) next to the 70Se (right). 

Here's the list with the files to look at, btw 21:00-6:30. Further analysis needs to be done offline. The slight frequency shift overnight made it a bit harder to see, unfortunately.

  186   Thu Jul 1 23:46:17 2021 IrisGeneralLess beam after gas bottle change?
Looks like there is a bit less beam now in the ring. I just looked at one spectra from before the gas bottle change and after...
  187   Thu Jul 1 23:54:43 2021 IrisGeneralLess beam after gas bottle change?
No, everything okay! Must have had a very good earlier run to compare.

  134   Thu Jun 24 22:05:11 2021 Helmut WeickAcceleratorLISE files for 72Ge, 70Se, 52Mn settings
This is just a Brho selection by the ESR based on SIS-energy used, 
energy-loss in target with calibrated thickness and momentum spread by the reaction (Goldhaber formula).
Production cross sections are by EPAX 3.1
  2   Wed Apr 28 09:36:39 2021 Helmut WeickSimulationsLISE file for fragments from TE3UF into ESR
Uncooled beam on target at TE3UF with dispersion and slit in TE beamlne and realistic injection into ESR.
Now tuned for 72Ge but can easily be modified to other fragment settings. 
The target thickness may need adjustemet after measurement.
The attched powerpoint file explains the settup a bit more.
  74   Sat May 8 11:42:21 2021 YuriAcceleratorKPs
EO1KP03 was on = -44.9 A
E01KP05 was off, now is on = 3.67 A
The beam is on the right frequency, but the width is still very broad.
  164   Thu Jul 1 01:35:15 2021 David, LilianaGeneralIon source change
Changing ion source, no beam expected for the next 30 minutes.

2:15--> Beam is back, intensity not as high as before but will increase in the next few minutes as the source gets hotter.
  40   Fri May 7 09:56:43 2021 YuriCalibrationIdentification Verification
With closed scrapers there are only a few weak lines.
Open temporarily all scrapers in the ESR to write down the frequencies.

Attached are two files with a proposed particle identification.
Different colors indicate different harmonic numbers

  144   Wed Jun 30 00:20:10 2021 Rui-Jiu ChenAnalysisID of 70Se setting on May
This is an old spectrum which was recoded on May.

This is the latest ID of 70Se setting.
  8   Thu May 6 00:32:57 2021 Helmut WeickSimulationsGICOSY file for TE beamline and ESR
This file has several options:
start in SIS, at TE3UF target or inside ESR, choose with GOTO LABEL (G L)after start system (S S).
Depending on the choice select different start beam parameters at top of file, others comment out.

There are also different optics setting with different quadrupoles:
- for TE beamline the standard and the mode by Hans for better focus on the target.
- for ESR a standard mode and variations of isochronous modes
also select by commenting in/out.

Input can be made also in units of K'L for fast import from parammodi, still by hand but with copy and paste.
One half of ESR is defined as a block, can be used more or less often (B I HALF ;)
  43   Fri May 7 10:46:40 2021 YuriAcceleratorGE02DS3HG
The scraper is blocked at -10 mm and -unfortunately- blocks the beam in the ESR. Uli Popp is taking care.
  170   Thu Jul 1 16:47:15 2021 Andrew NicRunsFrequency shift
The freqency suddenly shifted at time 16:11:47 and remained shifted until now 

The ESR status in the monitor stayed blue. No obvious sign that a magnet was down. The operators are checking

Sergey telephoned, he is also not sure but suggests stopping starting the ESR. We will wait for Yuri
