Experience gained during the recent operation of high power 11.424 GHz rf sources for accelerators led to new, stricter requirements for system components. One of the basic components of such a system is a mode converter that transforms the rectangular waveguide mode into the TE01 circular waveguide mode. With such a converter, it is possible to minimize the use of WR90 rectangular waveguide which was shown to be a weak part of the previous system at power levels higher than 100 MW and pulse lengths on the order of a microsecond. We used several methods to design a compact mode converter with extremely low parasitic mode conversion. These methods employ HFSS and include multi-parameter searches, concurrent optimization with a mode-matching code CASCADE, cascading of resulting S-matrices, and tolerance analyses. This paper describes the design methods and presents results. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR] |
