Development of a Monte Carlo simulation to study linear radiation position sensitive detectors

This work describes a special Monte Carlo program proposed to study the extension of light generation in a bar of plastic scintillator used as a linear radiation position sensitive detector. The configuration uses two photomultipliers (or sensors) in both extremities of the scintillator detectors. This program is able to estimate the following parameters: (i) the distance length between the primary photon interaction and secondaries scatterings inside the detector. This parameter enables the research to know how many parts the detector can be divided virtually, making it capable of working as a multidetector system, (ii) the capability to absorb the incident energy (intrinsic efficiency) , (iii) the distribution of the different interactions (photoelectric, Compton, Rayleigh and pair productions) and finally (iv) the program can be useful as a guide to choose the optimized size of the detector.
