Mon Mar 31 20:42:38 2025, H. Weick, S. Litvinov, Accelerator, fragment setting, E-SIS
|
~ 20:00 changed E-SIS to 524.0 MeV/u to get 194Pb at the Brho of the primary beam before (=7.2008 Tm).
which corresponds to gamma = 1.400 for 194Pb82+.
Before it was E-SIS = 480.5 MeV/u after Be-1839 mg/m^2 target Brho = 7.2014 Tm.

Tue Apr 1 02:37:28 2025, H. Weick, S. Litvinov, Accelerator, Isoc-setting +scrapers
|
First a setting with orbit bump for injection on central orbit was tried.
- quadrupoles tuned and scrapers optimized

Fri Apr 4 17:04:39 2025, H. Weick, S. Litvinov, Accelerator, slits after target, Bio_REM alarm
|
A Bio-REM detector on the roof of ESR caused an alarm and shut down the whole accelerator.
Too much primary beam going to ESR, noe we avoid it by catching the primary beam at TE4 slits.
The distribution on current grids looks liek in the LISE simulation, we cut at 5mm.

Fri Apr 4 17:10:35 2025, H. Weick, S. Litvinov, Accelerator, ESR scraper setting
|
the new scraper setting for good isochronicity but still acceptable intensity losses is:
Done at ~ 15:00 today.
GEEXDS1HA (outside) = -8 mm

Wed Apr 9 06:47:51 2025, Esther, Nikos, General, Brief beam interruptions
|
There was no beam from SIS between about 06:28 and 06:39.
Again from 07:02 to 07:11.

Mon Mar 31 17:46:21 2025, Esther, DAQ, NTCAP scaler assignment
|
The setup contains two NI-6612 I/O cards with BNC-2121 connector accessories that provide eight inputs each for TTL scaler signals.
[B]Important: When connecting scaler signals make sure that they are TTL (not NIM)![/B]

Wed Apr 9 11:18:27 2025, Esther, DAQ, NTCAP off, RSA triggers disconnected
|
The NTCAP computer and crate are switched off.
The triggers are disconnected from the RSAs, but they remain on. |

Fri Apr 4 18:38:52 2025, Dima, Zac, Sid, Kanika, Ragan, Shahab, Beatriz, DAQ, new file name and settings for 245 MHz
|
new settings:
1.8 seconds recording on 245 MHz on RSA02
|
|
Sat Apr 5 18:24:09 2025, Dima, Zac, Shahab, DAQ, RSAs stop again, due to misses
|
RSAs had to stop because the cycle of 1.8 came too often, both analyzers could not catch up with the file transfer.

Wed Apr 2 01:46:52 2025, Chris, Carlo, Zac, General, Beam loss
|
HKR just called to say a power supply to the SIS18 extraction kicker has failed.
The service person has been called and is expected to take ~1h to arrive and approx. ~2h to carry out the repair. |
|
Wed Apr 2 05:48:31 2025, Chris, Carlo, Zac, General, Beam returned
|
Beam was returned to the ESR at 05:11.
HKR said there had been some problem with one of the dipoles and in order to restore it a power supply had to be reset, which took some time.
