Description

An RF kicker is being developed to mitigate high-charge bunch tails that can induce quenches in the superconducting magnets of the Argonne Tandem Linear Accelerator System (ATLAS). Building on previous design, the dual-harmonic kicker incorporates an additional harmonic mode to minimize the kick to the bunch core while maintaining effective tail removal. The resonant structure has been redesigned to reduce the coil size, resulting in a more compact assembly, and to implement the coupling and tuning schemes compatible with dual-harmonic operation. This paper presents the recent mechanical layout refinements, updated electromagnetic simulations, and outlines the next steps toward prototype fabrication and experimental validation.
