Title: An Over-moded Fundamental Power Coupler for the ILC

Abstract

The current design of fundamental power couplers for the ILC are expensive and require excessively long conditioning times. The goal of this develoment is design of a coupler that requires little rf processing and is significantly less expensive to build than the present ILC coupler. The goal of this program is development of a new technology for power couplers.This new technology is based on the cylindrical TE01 mode and other over-moded technologies developed for the X-band rf distribution system of the NCLTA. During the Phase I program, a TE10 to TE01 mode transducer suitable for use as a part of a power coupler in the ILC will be designed, built and tested. Following a succesful test, prototype designs of the TE01 to cavity coupler and thermal will be produced. A detailed study of the suitability of this overmoded waveguide technology for the ILC power coupler will be provided in the final report. Development of over-moded power couplers for superconducting cavities could find application im many world-wide accelerator projects, such as SNS, Jefferson Lab upgrade, RIA, TESLA in addition to the ILC.
