Abstract

A liquid helium free superconducting magnet was designed and fabricated and for an application to a millimeter wave gyrotron and a peniotron. The magnet generates a magnetic field of 5T in a 100mm room temperature bore and has been continuously working for more than 5,400 hours without troubles. The magnet system was applied to the millimeter wave gyrotron experiments to confirm the stability of the magnet. In the experiments, stable operations of the gyrotron were achieved in the frequency range of 30 - 133GHz.
