Thu Apr 4 09:50:36 2024, CLW, First Si analysis 2024 run 6x
|
Au and Si29 runs normalised by proton number show consistency (dedicated pulses, example detector 4). Plots for tof spectra zooming on one resonance
and histogram of counts in this resonance divided by protons with statistical errors.
Plots were produced with the macros attached. |

Wed Nov 15 13:40:50 2023, Claudia, Determination of neutron capture yield and related corrections
|
Here are all the files needed for calculation of the yield. There is some information that still needs to be added to the energyandyield.c file, for
example the atomic mass of your target in amu, the neutron separation energy for the compound nucleus in MeV (this is needed due to using the Weighting
technique). Also, you need to add some lines to read the tof histogram, which will then be converted in a neutron energy hisogram and then divided |

Tue Nov 7 13:21:51 2023, Emma Walker, Si-30: Comparison between background corrected and uncorrected
|
Below are graphs for the comparison between background corrected and uncorrected spectra (weighted) for Si-30, Au20, Au22 and Sinatgood.
This is just for C6D6 detector 1 but all detectors are consisitent. All histograms have been rebinned by 100 for clarity. |
|
Mon Nov 6 11:13:11 2023, Emma Walker, Comparison of empty, ambient and sample- Si-30 16x
|
Below are graphs for each sample (weighted) showing the comparison between ambient spectra, empty/dummy holder and sample spectra.
All four detectors are shown for each sample (Si-30, Au20, Au22, Sinatgood).
All histograms have been rebinned by 50. |
|
Fri Oct 27 17:13:58 2023, Emma Walker, Si-30: Dedicated vs Parasitic before and after removal of ambient 14x
|
Below are histograms for the weighted spectra (with deadtime correction) with and without ambient for C6D6 detector 1.
For each sample the histogram with ambient is first and then without ambient (please ignore histogram titles).
The Dummy, Empty and C-nat have been rebined by combining 100 to 1. |
