This file really has the optics like used in the last ESR experiments.
Now the transmission is also a little bit better.

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.

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. 
The picture shows in red the dispersion curve for dp/p=0.1% and beam envelopes of 10 mm mrad.
So we can use scrapers in north or south arc to cut Brho. It should be done from both sides.
How much? Watch the intensity drop.
Best positions look at plot. Straight section outside for low Brho, arc outside for high Brho.
Could be EEXDS2HA and E02DSH (outside).

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.

There are also different optics setting with different quadrupoles:
- for TE beamline the standard and the mode by Hans for better focus on the target.
- for ESR a standard mode and variations of isochronous modes
also select by commenting in/out.

Input can be made also in units of K'L for fast import from parammodi, still by hand but with copy and paste.
One half of ESR is defined as a block, can be used more or less often (B I HALF ;)

There are several issues.

1. The stepper motor drive does not react from Device-Control, -> check controller in FRS Messhütte
2. They don't get a trigger, other grids in TE-line do -> check raw signals also in FRS Messhütte, ask Strahldiagnose
3. For less noise pockets of grids should be evacuated, but most likely the pump is still off or not even connected -> enter ESR and connect

Check also manual at https://web-docs.gsi.de/~weick/frs/current_grids.html
Below picture of no trigger shown in App. Usually it should say last trigger a few seconds ago and display some noise.

Injection was optimized before with Cu-40 mg/cm^2 stripper.
This reduces energy of 78Kr from 370 MeV/u -> 386.52 MeV/u.
To keep the same ESR injetion the SIS energy was raised with Be 10mm tatget.
For exactly 1850 mg/cm^2 a SIS-energy of 445.46 MeV/u would be needed. A scan of SIS energy resulted in 445.0 MeV/u as optimal.
This means target thickness is close to 1850 mg/cm^2, we can call it 1839 mg/cm^2.

We think we see the frequency range of A/q=2.25 at 243.1 MHz.
This would correspond to L=108.2m and E=386.4 MeV/u (gamma_t = 1.3955) at h = 126.
Path length is a bit short, for L=108.4m it should be 370.6 MeV/u. 
(later reanalysis shows the measured frequency corresponds to 108.38m, which is like expected)

We closed scrapers on arc outside and straight section outside to limit Brho from both sides.
GE02DS3HG = -35mm, GEEXDS2AH = -25mm

Expected frequencies see below:

Opened TE4 slits again to +/-10mm.

Then we tried different scrapers:
in south arc outside: E02DS3HG, cuts at ~ -25mm, at -15mm gone, leave at -35mm.

on straight section: EEXDS2HA cuts at ~ -25mm, leave at -25mm.

EEXDS1HA, closing it to -25mm revealed a double peak structure with distance just like the wanted isomer (-2.2MHz at h=211).
But it is present on all intense peaks at the same distance, so it must be an artefact of a strange isochronicity curve.
Closing it to -15mm even had only the smaller lower frequency line survive.
But then it must be also possible to have only the stronger line. leave at -25mm

This worked with scraper in north arc E01DS_H which can cut from both sides.
The insie can ve iused to cut the lower Brho, 
at -50mm still two peaks, at -45mm left peak almost gone, -40mm left peak gone but right still intense, leave at -40mm.

-> Lower Brho seems to be clearly related to lower frequency, higher Brho side is not so clearly related to frequency.

Measure in this setting, nice void at wanted frequency. But no isomers appear so far.
 

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.
There are two versions (for cooled beam with fixed v or uncooled (isochronous) 
with fixed average Brho, take the second (grey) column.
For larger frequency shifts harmonics will overlap.
You can add more isomers.

If gamma_t = 1.3955 Tm stays, we will need Brho = 6.21902 Tm for 70Se.
The corresponding ESR Brho setting will be a bit shifted.
It then requires E-SIS = 446.55 MeV/u to get 70Se to this Brho and gamma_t.

For pre-drilling with 78Kr beam at same Brho use 416.70 MeV/u.
But we could also make a quick try without tuning before, just change all energies.

Checked beam positions in beamline before ESR,
they all look the same as before, with direct Kr beam.
Compare with old elog entry #.
Also on Leuchttarget it is in the center like before.

This is just a Brho selection by the ESR based on SIS-energy used, 
energy-loss in target with calibrated thickness and momentum spread by the reaction (Goldhaber formula).
Production cross sections are by EPAX 3.1

The two grids do not work very well, one x position is opposite to the other.
But at least a guidance for the future, this was good injection of 78Kr with a thick Be target.

parammodi exports, E-SIS = 441.0 MeV/u with Be-1840 mg/cm² target in, isoc. ESR, at least we see fragments

Here are parammodi saves for TE-line and ESR for all four fragment settings:
For the first run of 72Ge (7.May) I do not have files.

I've written two scripts that others might find useful for the on-line analysis. 
  1. The first is a simple bash script that runs a for loop to run the e143_analyzer.py script for a sequence of start values (-s). You'll need to change the increment and 
start/end of the for loop to set the time resolution.
  2. The second is a root script that takes the above generated scripts, reads the histograms, and then fills a 2D histogram. You'll need to adjust the TH2 bin number to 
match both the bin number of the TH1s and the number of analysed files. I've included a print line to help identify the TH1 bin number.

To see the first results, I've attached a sum of July 1st 22-23h data. Sadly, I don't see any indication of the isomer, or at least the production is very low.

In compliment to Liliana's plots, this is the summed spectra I calculated from 0338 to 0507.

Following Xiangcheng Chen's analysis, I analysed 11 ms time slices separated by 25 ms to see the evolution of the potential isomer across the injection.

Attachment 1: Data from May 7th 19h-20h. -t 11ms progression from -s=5 to -s=5.175
Attachment 2: Data from May 8th 21h-22h. -t 11ms progression from -s=5 to -s=5.175

The extra resolution gained on the 8th (and potentially other settings too) make the isomer visible where it wasn't present on the 7th.
