| Abstract |
As a multi-charge-state, heavy-ion, superconducting accelerator with a folded geometry, FRIB faces unique beam loss detection and collimation challenges to protect superconducting cavities from beam-induced damage. Collimation is especially important in the Folding Segment 1 where the multiple charge states are created by a charge stripper and selected by a charge selector. The transported ECR contaminants, interaction with the residual gas, and beam halo due to stripping could induced significant beam losses in this region. We have simulated the potential beam losses and planned collimation accordingly. A layered loss detection network is also specifically designed to visualize potential blind zones and to meet the stringent requirements on loss detection. The related sub-systems are designed and procured and are introduced in this paper.
