 Sun May 9 20:34:47 2021, Rui-Jiu Chen, Analysis, Comparison of frequency spectrum between 72Ge and other isotope 6x
|
This some preliminary analysis results by using NTCAP data. The IQ rate of NTCAP is 20 MSamples/seconds. I analyzed data files recorded from May 7
17:39 to May 8 2:20. The frequency of 72Ge is bended by 4kHz at the beginning of some injections. In order to check whether this frequency bending is
due to isomer or unstable magnetic field. I compare the 72Ge with other isotopes. The similar bending was observed for other isotope in each
corresponding injections. It seems that bend is due to unstable magnetic field. |

Mon May 10 03:37:53 2021, Chris C, Analysis, isomer? or wishful thinking?
|
They are not easy to find, but we do occasionally see what might be the isomer. |

Hi, attached is the sum of all spectra from 1-2am on May 10th, on the 245 MHz detector. Takes me forever to download everything...
I used the same parameters as Guy and Xiancheng: LFRAMES = 512 (in analyzer); -t 0.011 (= 11 ms) -s 5 ... 5.175 s.
Resolution looks good... :-) |

Same as before, but for 410 MHz detectors.
Peaks visible in the 3rd-5th slice.

Peak still there, maybe a bit less than before.

The first good spectra after the gas bottle change is from 23:38:25 (on the 410 MHz Analyzer) |

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... |

Fri Jul 2 05:08:16 2021, 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. |

No isomer, I think :-( (Sorry, Wolfram!)
