Laszlo Varga | General | Study on scraping | |
A publication on scraping systems suggested by Siegbert.
In the study they have used cylindrical "high-quality" slits. "High-quality" stands for well polished surface
with surface roughness <50nm. The material of the slit is Tungsten Carbide. |

Laszlo | General | Status of the ESR | |
After two days of tuning the beam, yesterday evening (~8pm), it was found out that within one ESR pattern using the new control system the harmonics of the cavities cannot be changed. This gives us a fatal limitation, that we cannot go lower
than 10MeV/u with the beam energy.
-As a first attempt we try to reach this 10MeV/u with two steps deceleration (first to 30MeV/u). At this 10MeV/u we have the p,n channel opened as well, which based on TALYS gives significant, weird shaped background in the spot of the p,g
peak both in xy and xE histos.
-A second option would be that we inject the beam to ESR roughly at 330MeV/u. Then we can decelerate until 5MeV/u, but there is no stochastic, neither e-cooling available. This result to a "hot" decelerated beam with intensity factor 5 less
(in optimistic scenario). But for this the whole tuning phase (the first two days of the beam time) must be remade, we have to start basically from scratch.
It is "funny" that we have a very limited 5 days of beam time which is spent estimately >99% with, from the physics point of view, completely useless beam manipulation issues, which in a normal world must be done already in the engineering
beam time...
It is quite challenging to stay positive at the current status (not positive in the sense of the growing Corona-virus). |

Laszlo | | Si, Xrays target density spectra during 118Te afternoon measurement | |
We got 30 counts out of this afternoon 118Te run on our Si TargetON histo.
That 1 count at bin (6,10) I dont understand.
Now i can see peaks both at the 35 and 90 angle Xray spectra but not much on the 145 one.
At the end the target density stayed at 8.6E13. |

Oliver, Diego | General | SIS Pattern changed | 2021 |
The pattern in SIS was changed so that we get more injections into ESR. Before HTD had 9 seconds which resulted in a timeout in the ESR. Now HTD has 10 seconds which improved a lot... |

Shahab | Runs | SIS Kicker problem | |
After calling ESR on-call duty (M. Steck) he confirmed that the ESR is fine and suspected the SIS kicker modules.
SIS operators then checked and could confirm that module 5 is out of order and module 4 sometimes works sometimes not.
They asked me I said better to run as good as possible with lower number of modules until the end of experiment, then later change the module. because otherwise changing module might take time.
they tried to increase the kick angle to check if they can move the spot to the center.
some shots went well but mostly failed.
they decided to call the Rufbereitschaft.
meanwhile I started the run number 93 to at least collect some data from some of the correct shots.
if counts are too high I will stop it.
let's see. |
