    "abstract": "Our gyrotrons developed in Fukui University, Research Center for Development\nof Far Infrared Region (FIR FU) are high frequency, medium power gyrotrons as\nmillimeter to submillimeter wave radiation sources for application to new\nfar-infrared technologies including plasma diagnostics. We have already\ndeveloped Gyrotron FU Series which consists of 8 gyrotrons. The gyrotron series\nhas achieved frequency tuneability in wide range (from 38 GHz to 889 GHz). The\nhighest frequency is corresponding to a wavelength of 337 micrometers. This is\na current record for high frequency operation of gyrotron. Recently, we have\ndeveloped a high harmonic gyrotron with an axis-encircling electron beam and a\nTHz gyrotron with a pulse magnet. In this presentation, the present status of\nGyrotron FU Series is described.",
