Abstract

In this study, we have designed and manufactured not a present elliptic cavity but a circular cavity and we have experimented the operational characteristics. As a result, we obtained the maximum efficiency of 2.1 %. It didn't have any difference compared with elliptic cavity. A circular cavity is much more compact, so far easier to be manufactured than a elliptic cavity. And it can be made at a low cost. At the input energy, parameter $\alpha$, input voltage, and pulse width were in the same condition, we have decided to the optimization of the mesh number of a parallel-mesh circuit which was connected with main power supply.
