|
anything from RSA01-2025.04.01.02.54.25.976.tiq onwards is good data
recording parameters:
5 MHz with 6.25 MSPS, 2.5 seconds, analyzer span 100 khz, trigger at 5%
All analyzer times are now set to summer time
file time stamps are correct
settings are in the attached pictures. |

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
Then back to an ESR setting without this bump like last year.
- again quadrupoles tuned and scrapers optimized
This gave a good resolution in which the isomer should be resolved.
Just after this was achieved all resolution was lost.
Making the input for ESR setting again recovered it, now with slightly different scrapers.
Quads: K'L Q3D / Q6D = -0.3603263
Sext: K''L GE01KS2 = -0.14
GE01KS3 = 0.05
scrapers: GEEXDS1HA = -5 mm
GE01DS3HG = -70 mm
Details see paper scans below. |

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.
Keep target and beamlines and ESR the same, only SIS and TE-line before target is changed. |

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.
Important: When connecting scaler signals make sure that they are TTL (not NIM)!
Additionally, there is the possibility to assign data streams (eg clocks) from other modules in the NI chassis to scaler channels.
Below you find the assignment of the channels on the software side, including the internal clocks. This is important when analysing the .tmds files.
|
Channel | Input | Comment
| |
0 | 10 MHz clock | external (from NI 6674T timing module)
| |
1 | DC trafo | ion current in ESR
| |
2 | injection trigger | from Genesys (IO2 on sddsc221)
| |
3 | U-cooler | cooler voltage
| |
4 | I-cooler | cooler electron current
| |
5 | P-gun | pressure at e-cooler
| |
6 | 100 kHz clock | internal
| |
7 | 20 MHz clock | internal
| |
8 | software trigger | from Detectomer
| |
9 | PLEIADES outside |

9 | PLEIADES inside |

stop and delete NTCAP data from Weekend test
for now the NAS data2 bank has been flushed to make sure good operation for today's beam.
we have now 35 TB space on bank 2.
the recording will be done on the bank2 of the NAS.
There are still some junk data on bank1, which we will remove later. |
