Title:	Final compression beamline systems for heavy ion fusion drivers
Abstract:	We have identified a general final compression section for HIF drivers, the section between accelerator and the target. The beams are given a head to tail velocity tilt at the beginning of the section for longitudinal compression, while going through bends that direct them to the target at a specific angle. The aim is to get the beams compressed while minimizing the centroid offset after the bends. We used the specific example of a 1MJ driver with 500MeV Rb+1 ion beams. We studied the effect of minimizing dispersion using different bend strategies, and came up with a beamline point design with adiabatic bends. We also identified some factors that lead to emittance growth, as well as the minimum pulse length and spot size on the target.
