摘要

本文对330ghz二次谐波TE94模式低压回旋管进行了非线性分析。在电子束电压为20 kV、电流为0.5 A的条件下，优化了相互作用电路，效率可达13.6%。在非线性分析的基础上，初步揭示了回旋管的模式竞争。该回旋管有望应用于500MHz动态核极化增强核磁共振(DNP-NMR)中。

Nonlinear analysis of a 330 GHz second-harmonic low-voltage gyrotron

The nonlinear analysis of a 330 GHz second-harmonic TE94 mode low-voltage gyrotron is presented in this paper. With electron beam of voltage 20 kV and current 0.5 A, the interaction circuit is optimized to achieve efficiency up to 13.6%. Based on nonlinear analysis, mode competition of the gyrotron is preliminarily revealed. The gyrotron is promising to be applied in 500MHz dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP-NMR).
