Development of CW THz gyrotrons in FIR FU

Abstract

A gyrotron with a 21 T pulse magnet achieved the breakthrough of 1 THz. This is the first result of high frequency operation in the world beyond 1 THz. In addition, new gyrotron series in FIR FU, University of Fukui, so-called Gyrotron FU CW Series is being developed. Such a present status of high frequency gyrotron in FIR FU will be introduced.
