Shahab, Michael, Yue, Zac, Carlo | DAQ | new RSA recording |
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. |

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

trying to do PID with some injections:
RSAs are still on winter time. they show summer time but files have winter time.

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. |
