摘要
High frequency, medium power gyrotrons (Gyrotron FU series) have been developed at Fukui University as radiation sources covering a broad frequency band from millimeter to submillimeter wave region. Conversion from gyrotron output of circular waveguide mode into Gaussian-like beam is useful for applications of gyrotron to a wide field. High mode purity output is necessary for an effective conversion. In order to improve mode purity, a nonlinear cavity which is designed using a scattering matrix code and exquisitely is fabricated is installed in the Gyrotron FU VA. The measurement of radiation patterns confirmed a high purity mode operation.
