 Wed Feb 6 10:16:09 2019, 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. |

Thu Mar 19 09:43:28 2020, 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.

Around 17:15 cooling had "unknown status 6"
At 17:21 cooling: "pumping in progress"
Around 17:41 cooling had "unknown status 6"

Sun Mar 22 17:47:27 2020, 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.

Sat May 22 17:13:48 2021, Laszlo, Detectors, Si position changed, 2021
|
| Si was moved from -25 mm to -19 mm before run 0072. |
|
Sun Mar 22 19:15:03 2020, Laszlo, , Si moved out of the ring, high voltage is switched off,

Sat May 22 17:15:26 2021, Laszlo, General, Scraper position, 2021
|
We found the beam axis with the scraper to be -17.5 mm.
The Scraper position set to +12.5 mm, 30 mm relative from the beam. |

Mon Mar 23 11:32:42 2020, Laszlo, General, SIS went down again,
|
| run101 is stopped |
|
Mon Mar 23 09:33:11 2020, Laszlo, General, SIS failure again!,
|
| run096 is stopped |

Sun May 30 00:14:58 2021, 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... |
|
Mon Mar 23 03:07:11 2020, 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.
|
|
Mon Mar 23 05:59:01 2020, Shahab, Runs, SIS Kicker ,
|
| SIS Kicker seems to be working properly. but we have to see how regularly it will work. |

Sat Mar 21 15:26:49 2020, Laszlo, General, SCRAPER is ON use again,
|
| Yuri puts back the scraper (Egelhof 1 - GE01DD1IG) into position = +19. (where it was in the evening) |
