Numerical simulation for longitudinal and transverse coupling motion in compact electron beam simulator for heavy ion inertial fusion

Abstract For heavy-ion beam driven inertial confinement fusion, space-charge-dominated beams are studied by a compact experimental device, scaled by electrons instead of heavy ions. In this study, space charge effect is investigated numerically in the compact electron beam simulator. Modeling of the compact beam simulator is studied, and a molecular dynamics simulation, which represent a so-called particle–particle model, is applied to the calculation of particle dynamics in three-dimensional space. A longitudinal-transverse coupling motion is observed in the multi-particle simulation result.
