Abstract
This paper presents a survey of the present theoretical understanding based on advanced
analytical and numerical studies of collective processes and beam-plasma interactions in intense
heavy ion beams for applications to ion-beam-driven high energy density physics and heavy ion
fusion. The topics include: discussion of the conditions for quiescent beam propagation over long
distances; and the electrostatic Harris instability and the transverse electromagnetic Weibel
instability in highly anisotropic, intense one-component ion beams. In the longitudinal drift
compression and transverse compression regions, collective processes associated with the
interaction of the intense ion beam with a charge-neutralizing background plasma are described,
including the electrostatic electron-ion two-stream instability, the multispecies electromagnetic
Weibel instability, and collective excitations in the presence of a solenoidal magnetic field. The
effects of a velocity tilt on reducing two-stream instability growth rates are also discussed.
Operating regimes are identified where the possible deleterious effects of collective processes on
beam quality are minimized.
