Abstract:
The requirement to match the longitudinal dynamics across the frequency jump in the superconducting linac result in a voltage and synchronous phase profile in the medium-beta elliptical cavities that make it difficult to design an optimal power coupler.
This note suggests using three families of power coupler in this section of the linac in order to ease the design of the coupler, and to result in significant RF power savings.
