|
After looking through >800 shots from Jul 2nd 21h to Jul 3rd 05h, we couldn't find a single example of a "smoking gun" isomer decay. I.e. I'm talking about
the examples Liliana posted earlier. We did find many examples (roughly 10%) where the ion track spontaneously
disappeared, but this shouldn't be the isomer as there was no frequency shift.

Here's a list of the spectra to look at for the potential isomer, taken btw 21:00 on July 2nd and 6:30 on July 3rd. Two examples attached.

Attached is an example for the possible isomer (on the left) next to the 70Se (right).
Here's the list with the files to look at, btw 21:00-6:30. Further analysis needs to be done offline. The slight frequency shift overnight made it a bit |

Sat Jul 3 04:33:50 2021, The remote Canadian eager beavers (Guy & Iris), Analysis, Slight shift in 70Se frequency
|
Looks like the beam is slightly drifting...the 70Se peak frequency is slightly shifted to the left, by ~0.5 kHz compared to earlier spectra. Might be a
problem with the analyzer (?) or the storage ring energy (slightly lower?)... nothing drastical but to be observed. |

Sat Jul 3 03:41:48 2021, The remote Canadian eager beavers (Guy & Iris), Analysis, Summed Spectra Summary
|
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.

| Attached are some single spectra with a rough attempt to group them according to the different ions that appear. |

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.

We tune back to 70Se.
The scrapers stay closed at EEXDS2HA=0 mm, EEXDS1HG=+5 mm

At 19:56 the DAQ is stopped.
The plan is to go back to the setting for Se.

at 17:20 intensity was suddenly reduced.
Operators checked. Intensity was a bit low and fluctuating for a while (8e8 to 1e9)
Intensity (1.5e9) was recovered at 18:16 |

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.
