Validation of Compton Scattering Monte Carlo Simulation Models [PDF]

, 2014
Several models for the Monte Carlo simulation of Compton scattering on electrons are quantitatively evaluated with respect to a large collection of experimental data retrieved from the literature. Some of these models are currently implemented in general

New CAD modeling approach in Geant4 with half-space CSG

Frontiers in Nuclear Engineering
Geant4 offers constructive solid geometry (CSG) for modeling detector geometries, but representing intricate computer-aided design (CAD) structures can be cumbersome. This article presents a novel approach that overcomes this limitation.

Influence of backscattered electrons on exit beam of miniature transmission X-ray tube using Geant4

He jishu
BackgroundWhen an X-ray tube operates, a large number of backscattered electrons are generated inside the tube. Under the influence of the electric field inside the X-ray tube, these backscattered electrons are pulled back to the anode target by the ...
