We present the first experimental results of the study on a novel second harmonic THz-band double-beam gyrotron. The tube has demonstrated a stable single-mode operation with output parameters that are appropriate for the next-generation 1.2 GHz dynamic nuclear polarization-nuclear magnetic resonance spectroscopy. Besides the design mode (TE), a series of other fundamental and second harmonic modes have been excited. This makes the new gyrotron a versatile radiation source, which can be used also in other applications of the high-power science and technologies.
我们展示了对一种新型二次谐波太赫兹波段双束回旋管研究的首批实验结果。该管子已证明能稳定单模运行，其输出参数适用于下一代1.2吉赫兹动态核极化 - 核磁共振光谱学。除了设计模式（TE），还激发了一系列其他基波和二次谐波模式。这使得新型回旋管成为一种通用的辐射源，也可用于高功率科学技术的其他应用中。
