摘要
随着应用于DNP-NMR回旋管向着高频段发展,回旋管需工作在高次谐波以降低对磁场要求,由此带来更加剧烈的模式竞争。本文选取460GHz回旋管,从起振电流上具体分析了模式竞争及模式选取问题,具体分析了TE_(8,3+)模式和TE_(3,5+)模式的起振问题。
As the gyrotrons applied to DNP-NMR are developing towards high frequency, they work in high harmonic to reduce the magnetic field, while this will result in sever competition. This article selected 460 GHz gyrotron to analysis mode competition and mode selection. Especially, analysis the start current of TE_(8,3+) and TE_(5,3+) in detail.
