Abstract

In gyrotron devices, pitch factor and efficiency are directly proportional. When the pitch factor is increased, however, a larger starting current is needed. The available power supply thus limits the pitch factor and subsequently, the efficiency of the device. The present invention is a gyrotron device in which the pitch factor is adjustable. When starting the gyrotron the pitch factor is set to a low level and only a small starting current is required. After the device has been started, the pitch factor can be increased to increase the oscillation efficiency.
