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