NRL Compact Accelerator Theory Studies
Abstract
NRL compact accelerator theory studies in support of the Spiral Line Induction Accelerator (SLIA) and the Recirculating Linear Accelerator (RLA) are summarized in a series of short papers. The first of these papers describes the ELBA three-dimensional beam simulation code, a particle code which has been used to model beam stability and transport in both accelerators. The second paper presents and analytical model for the dangerous three-wave electromagnetic instability and defines parameter regimes for the SLIA where the instability can be completely stabilized. ELBA simulations of the SLIA in the various stability regimes, described by the analytical mode, are described in the next paper. The fourth paper includes additional ELBA simulations of beam transport in the SLIA, demonstrating that high eccentricity equilibria can lead to serious emittance growth. The effects of axisymmetric ion channel motion on beam transport in the RLA are discussed in the next paper. The sixth paper describes ELBA simulations of erosion and off-axis drifts in both straight and curved sections of the RLA. The final paper discusses the various atomic and surface plasma processes which may occur in compact accelerators. Keywords: Compact accelerators, Charged particle beams, Relativistic electron beams, Stellarator fields, Ion focused regime, Emittance growth.
