Abstract
Beam extraction simulations for high-voltage, immersed source accelerators are compared with analytic theory and experiment. dynadisc, a new nonlinear beam propagation code, is described and applied to the initial few meters of propagation in 1 atm air. The dynadisc results indicate that filamentation is the fastest growing instability. The filamentation changes the beam current density profile from an annular to a quasi-uniform distribution.This publication has 6 references indexed in Scilit:
