The development of a high current, heavy-ion beam driver for inertial
confinement fusion requires a detailed understanding of the behavior o
f the beam, including effects of the strong self-fields. The necessity
of including the self-fields of the beam makes particle-in-cell (PIC)
simulation techniques ideal, and for this reason, the multi-dimension
al PIC/accelerator code WARP has been developed. WARP [1] has been use
d extensively to study the creation and propagation of ion beams both
in experiments and for the understanding of basic beam physics. An ove
rview of the structure of the code will be presented along with a disc
ussion of features that make the code an effective tool in the underst
anding of space-charge dominated beam behavior. Much development has b
een done on WARP increasing its flexibility and generality. Major addi
tions include a generalized field description, an efficient steady-sta
te modeling technique, a transverse slice model with a bending algorit
hm, further improvement of the parallel processing version, and capabi
lities for Linking to chamber transport codes. With these additions, t
he capability of modeling a large scale accelerator from end-to-end co
mes closer to reality. Published by Elsevier Science B.V.
