摘要

为了满足高功率微波源的需求，本文制作了一种q波段100 kW连续波回旋行波管（gyrotron travel wave tube，陀螺行波管）。阴极涂层薄膜技术的应用大大提高了电子发射的稳定性和均匀性。该设备的功率容量是评估使用有效的热管理方法。实验结果表明，在56 kV-7.9 a的电子束驱动下，陀螺行波管在49.5 GHz时的最大连续波功率为115.6 kW，增益为54.9 dB，效率为26.1%。该设备长期稳定运行，性能处于当前技术的前沿。

High-Power 100 kW CW Q-Band Gyro-TWT: Performance and Stability

To satisfy the demand for high-power microwave sources, a Q-band 100 kW continuous-wave (CW) gyrotron traveling wave tube (gyro-TWT) is fabricated and experimentally demonstrated in this letter. The stability and uniformity of electron emission are greatly improved through the application of cathode coating thin-film technology. The power capacity of the device is assessed using efficient thermal management methods. Experimental results show that the gyro-TWT, driven by a 56 kV-7.9 A electron beam, achieves a maximum CW power of 115.6 kW, a gain of 54.9 dB, and an efficiency of 26.1% at 49.5 GHz. The device operates stably for a long time, with performance at the forefront of current technology.
