摘要：

CPI, partnered with Bruker, has been engaged in a long-standing program to develop gyrotrons for Bruker's commercial dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) spectrometers. The Bruker-CPI development program, started more than 15 years ago, has resulted in a family of robust and reliable continuous wave (cw) high-frequency gyrotrons. The design features and measured performance of the Bruker-CPI gyrotrons at 263, 395, 527, and 593 GHz, all of which have demonstrated over 50 W cw output power in high-quality Gaussian beams, will be described.
