Observation and mitigation of image distortion in high energy electron radiography

In this study, the Monte Carlo simulation of electrons penetrating a standard 100-mesh copper grid was performed using GEANT4. The ASTRA code was employed to conduct a beam-tracking simulation of the imaging system using the measured PMQ field maps. The beam optics was conducted by COSY Infinity. The images derived in experiment were processed with ImageJ. The dataset includes the GEANT4 results, ASTRA code, COSY code and the measured field maps.
