Charge stripper effects on beam dynamics in the 180-degree bending section of the RISP linac

摘要

The RAON, a superconducting linear accelerator for RISP (Rare Isotope Science Project), will use a charge stripper in order to increase the charge states of the heavy ions for effective acceleration in the higher energy part of the linac. The charge stripper affects the beam distribution by scattering the heavy ions as they go through the charge stripper. Moreover we have to select and accelerate proper charge states between 77+ and 81+ for the case of a uranium beam in order to satisfy the beam-power requirement at an IF (inflight fragmentation) target. This work focuses on how the beam dynamics are affected by the charge stripper in the 180-dgree bending section.
