Philipp, Marta | General | Screenshot |
The signal of the transformer on the lower right panel is not really beam related. It is mostly noise. Changes are not so expected with this low beam intensity |

Helmut Weick | Simulations | frequency list for 70Se setting |
EXCEL table with all possible fragments injected into ESR.
The path length in ESR, gamma_t and harmonic are adjusted to the 72Ge data.
Some lifetimes are limited but all intense lines are >30s in lab system.
There are two versions (for cooled beam with fixed v or uncooled (isochronous)
with fixed average Brho, take the second (grey) column.
For larger frequency shifts harmonics will overlap.
You can add more isomers. |

Helmut Weick | Accelerator | 70Se setting |
If gamma_t = 1.3955 Tm stays, we will need Brho = 6.21902 Tm for 70Se.
The corresponding ESR Brho setting will be a bit shifted.
It then requires E-SIS = 446.55 MeV/u to get 70Se to this Brho and gamma_t.
For pre-drilling with 78Kr beam at same Brho use 416.70 MeV/u.
But we could also make a quick try without tuning before, just change all energies. |

Akash, Nic, Jelena, Zsolt | General | SIS, ESR time structure changes |
The structure of SIS extraction seems to have changed a little...also for ESR injection.
In the span of a few minutes both the structures changed again...to look more like in the previous shifts, with lesser or no negative component. |

Akash, Nic, Jelena, Zsolt | Accelerator | No Beam! |
08.43am: Beam stopped. HKR looking into it. Reason: they mentioned they don't know yet!
10.10am: SIS resumed operations. However, there are some issues with magnet power supplies for ESR and hence we still don't have beam. HKR member went to look for power supply expert.
10.15am: There were some random triggers coming from ESR, which resulted in files being written. To avoid this, the scope trig (both scopes) were taken out. As soon as the beam comes in 'properly', I will reconnect the trig in to the scopes (-akash).
10.40am: They sent something to ESR but it does not make sense...so HKR has called an ESR expert (Sergey).
11.30am: Yuri is here and trying to sort out the issue- no data being written yet. |

Yuri | Accelerator | KPs |
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. |

Checked beam positions in beamline before ESR,
they all look the same as before, with direct Kr beam.
Compare with old elog entry #.
Also on Leuchttarget it is in the center like before. |
