Abstract

A novel approach of sheet electron beam transport under uniform magnetic field through a tunnel of particular shape and size is described here. The space charge field for rectangular beam trough rectangular tunnel, elliptical beam through rectangular tunnel, elliptical beam through elliptical tunnel is analyzed numerically. This analysis shows that component of space charge field along direction of beam width (x-axis) reduces significantly and varies nearly linear with x by transporting elliptical beam in elliptical tunnel and keeping tunnel walls very close to beam. Simulation result of OPERA 3D software and CST particle studio shows that stable transport of intense sheet beam through an elliptical tunnel under uniform magnetic field is possible.
