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).
3) Beam-time coordinator suggests to run until the gas is over, i.e., up into the weekend.

So far, we keep the setting as it is and wait for experts to come in. 
Few spills are missing from time to time. One of the peaks stays usually in the spectrum when this happens. 
Analysis of the last hours is being performed by the remote shift, in case it is useful. Some plots in telegram. 

Beam energy to be increase to move Mn into the ring. 
First step we set the energy to 445 MeV. 
The effect of the change can be seen on the plot: Right is how it was before and left after the change. 

still in the search of 70-Se

The tune last night was unfortunately not to 52Mn. The two "isomers" that were identified are instead 45Sc and 75Br. But separation looks okay. ESR morning shift should try to tune to 52Mn to identify the 21-min isomer at 378 keV.

Uploaded some pictures to prove that we were not asleep :-) but they are of limited use...at least my analyzer script and wget works now !! 

Same as before, for 0-1h on July 2nd

The last hour before the gas bottle change is summarized here. 
The first pic shows the 410 MHz spectra taken from 22-23h on the 410 MHz analyzer, in time slices of 0.1 sec from 0s-2s.
The second pic shows the spectra in 20ms slices from 1s-1.16s.

The third spectra was taken in May, for comparison.

I don't think we see anything...

Same as before for 4-5h and 5-6h.
No isomer, I think :-( (Sorry, Wolfram!)

To summarise the method of bulk summing the spectra, I've created frequency vs time spectra by using the e143_analyser.py script to stack a series of -s slices. I applied it to some of last runs data with 72Ge, to the 72Br data, last night's less-scraped 70Se, and tonight's more-scraped 70Se, respectively.

A few comments: the 72Ge isomer trail is obvious, but I would never have found it in this total sum if I didn't know where to look. I had to turn up the contrast a lot before it was visible. The 72Br isomer is less obvious than in the single particle tracks, but it too is obvious. You can see that the peak is wider to left at the injection, and 
then narrows out as the isomer decays. This is what we would see if the two peak weren't well resolved.
With that in mind, the 70Se data is challenging. We've established the broad peak is not the isomer as it is not present in the 245MHz detector., and the many single lines seen in the well-scraped data correspond in frequency exactly to this broad band. The 70Se peak doesn't get broader at the base at injection like 72Br, and there isn't any 
line visible in the sum in between. I was nervous that the contrast might be the problem like with 72Ge, but I turned up the contrast on the less-scraped data, but no signal emerged.

So I conclude that if the 70Se isomer is to be found, it needs to be done on a shot-by-shot basis with comparison to the sum to see if it matches the intruder broad peak.

Here's a picture with all injections with an ion in the spectrum (empty ones were removed- list below). The time slices are 0-0.5-1-1.5-2s, then in 0.2s steps up to 3s. Not really anything to see :-(  The previous shift was right, looking at single spectra might be more useful. I'll group the pictures and upload some "interesting" ones.


Here is the list of spectra btw 21-23:59 which we have removed since they were empty or had just an ion on the far left side:

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.

Thickness of the Carbon target in the TE line has been measured by centering the primary 78Kr beam in the ESR:
Beam energy 370 MeV/u, with thin stripper, ESR energy 368.65 MeV
Adjust beam with "thick" target to keep ESR energy at 368.65 MeV/u -> Beam energy 445 MeV/u
Energy loss 75+1.35=76.35 MeV
Target thickness : 9.97 mm
