摘要：
CPI is currently involved in the design and development of gyrotron oscillators and amplifiers for a variety of applications. A family of low-power continuous wave (cw) gyrotrons for commercial dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) spectrometer is currently in production. Key features, as well as results from the experimental demonstrations of low-power gyrotrons at 263 GHz, 395 GHz, 527 GHz, and 593 GHz for this application will be discussed. In addition, megawatt class gyrotrons at 117.5 and 140 GHz are in production for tokamak and stellarator electron cyclotron resonance heating (ECRH) and electron cyclotron current drive (ECCD) systems. Design philosophies and design challenges, operational experience, as well as the results of experimental demonstrations at the fusion facilities will be presented.
