Abstract

Preliminary designs for the next large accelerator experiment envisioned for the Heavy Ion Fusion program, the IRE (Integrated Research Experiment) use an induction linac to accelerate multiple space-charge-dominated ion beams to an energy of several hundred MeV, and focus them at a target. This paper examines the effect of beam and quadrupole misalignments on beam emittance in the IRE. The dependence of the centroid orbit on the scaling of focusing parameters with z is analyzed. PIC simulations including misalignment give acceptable emittance growth for present IRE designs
