Abstract

The design of both higher order mode (HOM) and fundamental power (FP) couplers for a unique New Low Surface Field (NLSF) cavity is presented. Here we present a study which uses ILC baseline couplers. The Balleyguier method of calculating external quality factor is used and the results validated using both Microwave studio and HFSS.
