On a possibility to decrease magnetic intensity in microwave/DC cyclotron wave converter

This paper discusses CWC which uses two microwave cavities having uniform and quadruple electric fields in the interaction gaps which makes it possible to reduce magnetic intensity in two times. CWC demands magnetic intensity, which corresponds to the cyclotron frequency /spl omega//sub c/ equal to the frequency /spl omega/ of external microwave power source. This requirement (/spl omega//sub c/=/spl omega/) usually creates essential technical problems, especially in the short centimetric and millimetric wavebands.
