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.
Scrapers:
E02DS3HG -> -40 mm
EEXDS1HG -> +5 mm
EEXDS2HA -> 0.0 mm
One sees probably a decay of 100 keV isomer, see the attached figure at about 18 s
We will run a few hours with this setting |

Helmut, Yuri | Accelerator | move scrapers to see effect on unknown lines |
We close the arc inside and straight section inside scrapers to narrow and cut the 70Se line.
Then look what the other lines left of 70Se will do.
1st series with E01DS_HI
-58 - intensity as before
-52 - still as before
-50 - still full
-45 - less intensity but about same width
-40 - almost gone
0 - gone
-58 - back to old position
2nd series with EEXDS1HG
16.0 - full
15.0 - full
12.5 - less
10.5 - less intensity
9.7 - appears only sometimes
8.2 - gone
10.8 - middle intensity and more narrow, measure for a while |

The remote Canadian eager beavers (Iris and Guy) | Analysis | 00h to 05h Summed Spectra |
Using the scripts I posted previously, I summed 5.5 hours of data from midnight to 5:30 July 2nd CEST.
I used 10ms time steps for better time resolution, but that did leave questionable frequency resolution. If anyone would like to see higher resolved frequency plots for the
full 5 hours, let me know.
I've attached the spectra from 0s to 4s for the 410MHz and 0s to 2s for the 245MHz, including zooming in on the injection timing.
Given that we are summing 5 hours of data so the background is very smooth, I can only conclude that either the isomer doesn't exit, we cannot resolve it, or we are
producing incredibly low amounts such that the search needs to be needle in a haystack. |

Guy Leckenby (Canadian beaver team) | Analysis | e143_analyser.py Summing Script |
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. |
