Optimization of a Hornyak-Button Detector for Fast-Neutron Detection

As part of an ongoing program to improve the fuel-motion capability of the fast-neutron hodoscope, a response model has been developed for the Hornyakbutton detector. The model provides a description of the efficiency and gamma sensitivity of a Hornyak button in terms of detector parameters such as scintillator concentration, grain size, length, and transparency. It is possible using this model to quantitatively choose detector parameters for the Hornyak button.
