Multiple user beam distribution system for frib driver linac

The proposed Facility for Radioactive Ion Beams (FRIB) [1] will deliver up to 400 kW of any stable isotope to Rare Isotop Beam (RIB) production target. Operational efficiency could, under certain conditions, be improved by a system that can distribute the beam current, variable in a large dynamic range, to several independent targets simultaneously. A possible FRIB Beam Switchyard (BSY) utilizes an RF kicker with subsequent magnetostatic septum system to split the beam on microbunch to micro-bunch basis. The micro-bunches can be differentially loaded at the front-end of the Driver Linac [2]. The detailed analysis of the beam dynamics performance in the proposed BSY system is presented.
