| Abstract |
The FRIB heavy ion superconducting linac will present the highest peak power hadron beam facility, with beams carrying >400 kW power with kinetic energy >200 MeV/u. Fast protection systems are required to detect and remove beam within 35 us. Detection of beam losses in the low energy linac segment is confounded by two effects: small fluxes of secondary radiation from beam impacts, and large fluxes due to cross-talk from neighbouring, higher energy linac sections. We describe a machine protection scheme based on multiple families of diagnostics and diagnostic networks. On-going fault mode studies are utilised to assess risk and to assist in the definition of specific detection networks for high reliability and responsivity.
