Description
An RF kicker is being developed at Argonne Tandem Linear Accelerator System (ATLAS) to eliminate satellite bunches formed after the RFQ. These satellite bunches can quench the downstream superconducting magnets. Building on previous design, the dual-harmonic kicker incorporates an additional harmonic mode to minimize the kick to the bunch core while maintaining effective satellite 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. We present recent mechanical-layout refinements, updated electromagnetic simulations, and the next steps toward prototype fabrication and experimental validation.
