Parallel Bias Vs Perpendicular Bias of a Ferrite Tuned Cavity for the TRIUMF Kaon Factory Booster Ring.

摘要

The RF cavity reference design from the Kaon Factory booster rings is a double gap drift-tube cavity with parallel biased ferrite tuners to vary the frequency from 46 MHz to 62 MHz. LAMPF has developed a single gap cavity with perpendicularly biased ferrite to vary the frequency from 50 MHz to 60 MHz. Measurements on the LAMPF cavity have indicated that their frequency range could be extended to cover our requirements while still maintaining a reasonable magnetic Q. The analysis and comparison of the RF circuit and the AC magnetizing circuit for both designs are reported. 14 refs., 6 figs. (ERA citation 13:049400)
