Abstract :
A ultra high power gyrotron is being developed in millimeter and submillimeter wave region. The gyrotron is large orbit gyrotron (LOG) using an intense relativistic electron beam (IREB). A pulsed power generator "ETIGO-IV" is applied for IREB generation. A first prototype LOG was constructed for fundamental operation. The output characteristic of the LOG achieves 143.6 GHz and 9 MW at the fundamental. Corresponding cavity mode is TE14. Cavities for 2nd and 4th harmonic operations were designed by numerical simulation. The progress of development for prototype LOGs is presented.
