The comparison in counts from PYXIS detector prototypes and MoNA detector bars

The PYXIS neutron detector, comprised of a hydrocarbon scintillator and 2 multianode PMTs, was designed to be essentially a compact prototype of the individual MoNA bars, enhancing the position resolution providing extremely detailed decay energy spectra for neutrons, and an extremely useful resource for calculating the angular distributions. During recent MoNA experiments at FRIB, data was collected for a one hour duration “runs” from a beam cocktail consisting of primarily the heavy isotope Al-38 at a rate of 169pps and subsequently had the data from cosmic ray runs subtracted to minimize noise, giving us a histogram consisting of a pedestal and a neutron peak. Similar data was extracted from the MoNA bars, the difference being an extreme difference in counts, due to the PYXIS having only 3% of the volume that the MoNA bars possess. The goal of my study is to compare the performances of the PYXIS prototype to a MoNA bar that are closest to each other and extract a ratio of their count values.
