The ratios for BCT/PKUP for Si, Au20, Au22, Dummy, Empty and Sinat goodfellow have been plotted. Also included is the normalised counts (counts/BCT) with all 4 detectors on one plot. Apologies there is not a legend, however det1 is red, det2 is green, det3 black and det4 blue. 'counts' for Si was integreated over the Si resonance, for Au it was integrated over the largest resonance. For Dummy, Empty and Sinat the counts were integrated over a large range of 1e+5 to 1e+7ns. The Sinat resonance was too small for adequate statistics to only integrate over the resonance hence why a large range was used. 

The EAR1 ratios of BCT/PKUP, BCT/SILI and PKUP/SILI plotted for each run for samples Si, Sinat goodfellow, Au20, Au22, Empty and Dummy. 

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. 

Calibration parameters for each detector:

A linear function was fitted to the reference point channel (from experimental histogram) and reference point energy (from simulation histogram). The reference point 'r' was r=mean+(FWHM/2) for a gaussian fitted to each compton edge. 

The comparrisons between the calibrated experimental and simulation histograms has been attached. P1 (left) and P2 (right) on the Y88 hisograms indicate whether the histograms were scaled with respect to the leftmost or rightmost compton edge (only to allow easier comparrison).

8 sTED + 2 C6D6

C6D6: distance = 14 cm, angle = 135 degrees

sTED horizontal ring, distance for each detector from target = 4.5 cm. sTED labeled 8 in the DAQ is actually sTED #9 at n_TOF (actual sTED #8 showed no signal)
