Analysis of Radiation Pattern of 300 GHz CW Gyrotron FU CW I
300 GHz CW gyrotron FU CW I has been developed and installed in University of Fukui. Performance test has been carried out and the maximum power of 1.75 kW / CW has been attained. The radiation pattern of the output beam has been measured in detail with an infrared camera. It has been confirmed that the output beam propagates as a Gaussian beam with high purity. However, the output power is radiated into multiple directions within a range of the magnetic field strength at the cavity, which indicates simultaneous oscillation of competing cavity modes.
