A high-position-resolution trajectory detector system for cosmic ray muon tomography: Monte Carlo simulation

Abstract

Purpose

The research focuses on the related designing and simulating the high-position-resolution trajectory detector system based on cosmic ray muon tomography.

Methods

The energy deposition of muon in the detector varies with the length of the ionization path.

Results

The simulation of the submillimeter detector system was designed for muon imaging. The optimal position resolution of the detector reached 0.6 mm.

Conclusions

The entire research process includes the selection of analysis of parameters affecting system design, designing of two high-position-resolution detectors based on plastic scintillators, implementation of different imaging algorithms and image quality assessment based on different imaging models. It provides a solution based on high positional resolution plastic scintillator detectors for cosmic ray muon scattering imaging.
