Development of an Excitation and Detection System of Electron Bernstein Waves in LATE

抄録

In order to detect the wave pattern of electron Bernstein waves (EBWs), an excitation and detection system has been developed in Low Aspect ratio Torus Experiment (LATE). The system consists of a waveguide launcher with arbitrary polarization, a specially designed five-pin probe antenna, a two-dimensional (2-D) mechanical probe driving system, and a homodyne-type mixer circuit. The excitation and detection system has been tested in the air and shows reliable results.
