TL;DR

This paper investigates the optimal angle-cut of collimators in high-energy proton radiography using Monte Carlo simulations to improve image contrast for various energies and objects.

Contribution

It introduces a method to determine the optimal collimator angle-cut for different energies, enhancing image quality in proton radiography.

Findings

Optimal angle-cuts vary with energy and object type.

Monte Carlo simulations effectively determine collimator parameters.

High contrast images are achievable with the proposed angle-cut selection.

Abstract

The use of the minus identity lenses with the angle-cut collimator can achieve high contrast image in high-energy proton radiography. This article presents the principle of choosing the angle-cut aperture of the collimator for the different energies and objects. The numerical simulation using the Monte Carlo code Geant4 has been implemented to investigate the entire radiography for the French test object. The optimum angle-cut apertures of the collimators are also obtained for different energies.
