Geant4 simulation of plastic scintillator strips with embedded optical fibers for a prototype of tomographic system

The response to cosmic muons of plastic scintillator strips, with and without wavelength shifter fibers embedded, read out at both edges by photomultipliers has been studied through detailed Geant4 simulations, with the aim of studying the light collection at the module ends under different conditions. The performed simulations, validated and tuned with data coming from a module prototype, could serve as an important guide for the design of a tomographic system based on cosmic ray muons.
