QUARTZ  A numerical simulation of an asymmetric electrostatic accelerator
Abstract
The QUARTZ computer code has been developed for modeling neutral beam injectors, including steering effects produced by offsetting one or more accelerating electrodes. The features of the code are (1) use of a finite element code to obtain solutions of Poisson's equation in an asymmetric, threedimensional volume, (2) inclusion of space charge neutralization by electrons, and (3) inclusion of ion space charge through an iterative procedure. The physics of the problem, numerical techniques, and preliminary results are discussed.
