Operation of a 95 GHz 100 kW Gyrotron in a High-Tc(BSCCO) Magnet

Results of simulation and testing of a gyrotron in a high-temperature superconducting magnet are described. The high-temperature magnet was designed as a replacement for an existing low-temperature magnet. Magnetic materials were incorporated into the high-temperature magnet´s cryostat, in order to achieve the fringing field profile required for compatibility with the gyrotron. Nevertheless, the shape of the original magnetic field profile could not be precisely matched, resulting in an 8% reduction in gyrotron efficiency. Magnet cooling power requirements were reduced by a factor of two, and charging time was reduced by a factor of 30
