Experiment Evaluation of Beam Characteristics in a Dual-Frequency kW-Class Gyrotron Cavity
Multi-frequency gyrotrons have become more attractive sources for magnetic fusion tokamaks. We report experimental study on a dual-frequency gyrotron (142 GHz and 208 GHz) for a possible application to electron cyclotron resonance heating (ECRH) and current drive systems. Low and high power performance tests of the cavity modes at dual frequencies have confirmed that the output beam quality reaches the design goals.
