Thu Jun 29 09:21:13 2023, Annie, Info on Samples
|
Both Au samples (20mm and 22mm) are single mylar.
Both Si30 (22mm) and natSi (20mm) are double mylar.
Empty is single mylar ONLY |

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. |

Fri Jul 28 12:19:10 2023, Michael Donnachie, EAR2 consistency checks, PKUP BCT SILI and normalised counts 10x
|
The EAR2 ratios of BCT/PKUP, BCT/SILI and PKUP/SILI plotted for each run for samples Si, Sinat, Au20, Au22 and Dummy.
Also included is the normalised counts (counts/BCT) with 7 detectors on one plot (STED8 was ommited). 'counts' for Si
was integreated over the Si resonance, for Au it was integrated over the largest resonance. For Dummy and Sinat the counts were integrated over a |

Mon Aug 28 14:07:23 2023, Michael Donnachie, EAR2 Experiment vs Simulated Amplitude Spectrums 28x
|
Attatched are the overlayed compton edges for the calibrated experimental and the GEANT4 simulations. Note p1 and p2 denotes the lower and higher energy
compton edges for Yttrium.
The experimental and simulated histograms are shifted in quite a few of these plots suggesting the calibration was not fully successful. |

Fri Jul 28 12:07:33 2023, Michael Donnachie, EAR2 C6D6 timeshift issues
|
There seems to be issues with the EAR2 C6D6 T histograms. For Au the earlier run seems to be shifted for detector 2 compared to the rest.
For Si plotted is 3 different runs 216123, 216128 and 216135 for both detectors. The histogram is messy but highlights that there
is a problem. The single Si resonace should be around 20 000ns and this is only the case for run216128. |

Tue Aug 29 10:32:35 2023, Michael Donnachie, EAR1 Parasitic vs Dedicated runs 6x
|
Below are the histograms of parasitic vs dedicated runs for EAR1. Also included are histograms with ambient background removed which closes the
gap between parasitic and dedicated histograms. This was preformed by scaling the ambient by counts by a multiplication of (dedicated or parasitic) bunch
number/ambient bunch number. There are no legends but the dedicated counts are in black and parasitic counts in red. Only included are C6D6 1 detectors |

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 |

Sat Mar 23 15:06:44 2024, Nick, Detector Setup - 28/29Si Campaign 2024 9x
|
Campaign started yesterday. C6D6s placed at 9 cm distance, angle 125 degrees w.r.t beamline.
Measured calibration sources: Cs137, Y88, AmBe, CmC. Measuring Si-nat over the weekend.
