Kanika, Sergey, Yuri, Wolfram, Michael, Shahab | Runs | Energy change +6 MeV/u |
We will now go up in energy to 447 MeV (+6 MeV) from the original energy
last file name with previous energy:
245: 2021.05.07.16.33.47.178

Iris | Runs | Example of possible 52.Mn isomer |
So the "isomers" pop up at ~-600 Hz and +580 Hz... is the -600 Hz on the left the 378 keV isomer (21 min) and the +580 Hz on the right the g.s.? |

Iris (Shahab, Jacobus, Chris G., Michele) | Runs | Example of possible 52.Mn isomer |
Short update from Yuri: these are not our isomers. These are 45Sc (left, 12 keV isomer not resolvable) and 75Br (center), and the right-most peak of the triplet is a satellite (has a different line shape, much narrower).

Iris (Chris G., Jacobus, Michele) | Runs | First 52Mn run (no 52Mn unfortunately) |
> Run E143-245 MHz-2021.05.09.01.17.42.265.tiq is the first run of the experiment on 52Mn.
And Run E143-410MHz-2021.05.09.03.27.37.368.tiq from 2021-05-09 03:27 is the first run on the 410 MHz detector. Started a bit later than the 245 MHz detector.

Andrew Nic | Runs | Frequency 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 |

The scraper is blocked at -10 mm and -unfortunately- blocks the beam in the ESR. Uli Popp is taking care. |

Helmut Weick | Simulations | GICOSY 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 ;) |

With closed scrapers there are only a few weak lines.
Open temporarily all scrapers in the ESR to write down the frequencies. |

David, Liliana | General | Ion 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. |
