The remote Canadian eager beavers (Guy &Iris) | Analysis | List of possible spectra with isomer decay |
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 harder to see, unfortunately.

The remote Canadian eager beavers (Guy & Iris) | Analysis | Closer potential isomer tracks |
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.
We did, as Iris mentioned, observe some line "in-between" the broad peak unique to the 410MHz, and listed them here (https://triumfoffice365-my.sharepoint.com/:x:/g/personal/dillmann_triumf_ca/EdKsMfSC3AlHopA36PdLBlsBE2MCSY0hh5qIsuau5HFBmg?rtime=Z2os4J492Ug).
I then proceeded to sum these files to see if they lined up. The result it attached, with the previous total sum from 21-00h Jul 2nd at the bottom for comparison. It seems the 70Se line has shifted, this is observed in the other shots too. However, despite the low
statistics, these other shots don't line up with the broad peak identified before, although they don't line up well with each other individually either.
In either case, we think these files might be worth offline analysis as they're the only possible hint of the 70Se isomer so far. |

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. |

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.
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. |

The remote Canadian eager beavers (Guy and Iris) | Analysis | Summed spectra 410 MHz from 21:00-23:59 (70Se) |
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:
