 Wed Apr 28 09:36:39 2021, Helmut Weick, Simulations, LISE file for fragments from TE3UF into ESR 
|
Uncooled beam on target at TE3UF with dispersion and slit in TE beamlne and realistic injection into ESR.
Now tuned for 72Ge but can easily be modified to other fragment settings.
The target thickness may need adjustemet after measurement.

Tue May 4 17:54:08 2021, Helmut Weick, Simulations, updated LISE file
|
This file really has the optics like used in the last ESR experiments.
Now the transmission is also a little bit better. |
|
Tue May 4 18:25:31 2021, Helmut Weick, Simulations, cutting of primary beam
|
The slits at TE4 and TE5 can be used to cut away the unwanted 78Kr beam (see pictures).
We do not want activation of the beamline. 78Kr35+ even has a chance of being injected. |
|
Tue May 4 21:49:04 2021, Helmut Weick, Simulations, cut Brho by scrapers
|
The dispersion from the production target into the ESR is not matched.
This is not good for momentum acceptance, but we anyway want to cut the acceptance.
Dispersion will oscillate with the tune of ESR. After 3 turns we expect a maximum dispersion.

Thu May 6 00:32:57 2021, Helmut Weick, Simulations, GICOSY file for TE beamline and ESR
|
This file has several options:
start in SIS, at TE3UF target or inside ESR, choose with GOTO LABEL (G L)after start system (S S).
Depending on the choice select different start beam parameters at top of file, others comment out.

Sat May 8 01:33:25 2021, Helmut Weick, Simulations, frequency list for 70Se setting
|
EXCEL table with all possible fragments injected into ESR.
The path length in ESR, gamma_t and harmonic are adjusted to the 72Ge data.
Some lifetimes are limited but all intense lines are >30s in lab system.

Fri May 7 04:01:51 2021, Shahab, Runs, Picture after scraping
|
this picture is after scraping by helmut, showing the 410 MHz detector, that is we would expect an isomer where the marker M1 is, i.e. at 2.2kHz on the
left side, which we unfortunately don’t see (yet). |

Fri May 7 04:26:54 2021, Shahab, Runs, 245 MHz resonator extra 20dB gain off
|
| made sure that the extra 20dB amplifier is off. |

Fri May 7 18:43:13 2021, Kanika, Michael, Shahab, Runs, cave M experiment needs more spills
|
our pattern causes beam loss while scanning the biological probes in the Cave M bio experiment. They loose every other spill due to high request rate from
ESR.
