Simulation analysis of electron imaging method based onMonte Carlo simulation and particle tracer software

We designed the radiography imaging system based on the high energy electron beam using theoretical analysis and numerical simulation, and optimized the parameters using Geant4 and GPT software. In the simulation we analyzed the parameters which affect the system space resolution and areal density resolution. With the ability to resolve the thickness of the sample, the result shows that the method can reach space resolution of m. It proves that the design satisfies the demand to image the sample of certain thickness and structure.
