Description
In high-duty-cycle and CW operation, 4-rod RFQs are limited mainly by heat removal from stems and the tuning plates. Local heating causes deformation, detuning and a degraded field distribution. Conventionally manufactured cooling channels are limited in their form and position by the manufacturing process.
This talk presents the development of a 4-rod RFQ prototype made by laser powder bed fusion (L-PBF) from pure copper and a copper alloy (CuCrZr). The conventional cooling channels are partly replaced by gyroid lattice structures inside the components. Gyroids offer a very large heat-exchange surface, are self-supporting during printing and leave the RF surfaces intact.
