Attached are two files with a proposed particle identification.
Different colors indicate different harmonic numbers |
Wed Jun 30 08:59:37 2021, Yuri, Accelerator, 70Se setting
|
X(9Be)=1.815 g/cm2 (adjusted in primary beam setting)
Gamma_t=1.3956

Fri Jul 2 13:10:00 2021, Yuri, Accelerator, Scrapers
|
12:46 moved the TOF detector scraper back to -11 mm |
Fri Jul 2 16:14:17 2021, Yuri, Accelerator, Scrapers 4 72Br
|
Starting 15:15
The scrapers are moved very much close to each other to eliminate all background particles and leaving basically single ions injected for 72Br. Do not
wonder, this means that also many empty files are created.
|
Fri Jul 2 20:33:44 2021, Yuri, Accelerator, 70Se setting with closed scrapers
|
We tune back to 70Se.
The scrapers stay closed at EEXDS2HA=0 mm, EEXDS1HG=+5 mm
"Single"-particle run |
Thu May 6 21:26:02 2021, Yuri et al., Accelerator, Energies
|
gamma_t = 1.3955
Br(72Ge) corresponds to 6.79575 Tm
E (Kr) at Br(72Ge) = 392.9 MeV/u

|
1) Over night the source was conservated. It is being restarted now.
2) The approximated amount of Gas in this bottle shall allow for running until tomorrow morning (~24 h). There is still another bottle in reserve (1 l)
and one reserve from GANIL (0.5 l).

Wed Jun 30 13:57:14 2021, Yuri, Sergey, Accelerator, sextupoles + scraper positions
|
After setting up on 70Se
Sextupoles were adjusted to optimize the resolution of the 70Se peak. Set values are in the ESR logbook.
The SIS energy was shifted up to increase the number of 70Se.

Sat May 8 17:29:54 2021, Yuri, Sergey, Wolfram, Michael, Shahab, Runs, recording Kr decay measurement on NTCAP
|
Uc = 250mA
decay Kr 78, 476 MeV/u
|
Sun May 9 13:53:07 2021, Yuri, Wolfram, Andrew, Liliana, Calibration, Change of energy: Back as before
|
After looking at the spectrum it was concluded that the same isotopes, and no more, could be identified.
Now we change the energy back to 441.7 MeV/u and will open the scrappers to see if Mn comes in.
|
Thu Jul 1 14:47:15 2021, Yury, Helmut, Accelerator, added high Brho scrapers
|
So far only scrapers for low Brho were used:
GE01DS_HI = -58mm (arc from inside) and
GEEXDS2HA = -11.2 (straight from outside)
