讨论了 W 波段回旋管行波管 (陀螺行波管) 的实验细节并给出了毫米波测量结果，该行波管使用在第二电子回旋加速器谐波下工作的螺旋波纹相互作用波导。已经通过实验验证了一种通过使用由长亚截止漂移部分隔开的两部分的交互电路来增加增益的方法。 10 mW 驱动源足以实现 3 kW 的放大信号输出功率。采用单级凹陷集电极和约 20 kW 沉积束功率的连续波 (CW) 操作被认为是 W 波段陀螺行波管的首次演示。
Experimental details are discussed and millimeter wave measurements presented of a W-band gyrotron traveling-wave tube (gyro-TWT) that uses a helically corrugated interaction waveguide operating at the second electron cyclotron harmonic. A method for increasing the gain by using an interaction circuit with two sections separated by a long sub-cutoff drift section has been experimentally verified. A 10-mW driving source was sufficient to enable an amplified signal output power of 3 kWs. The continuous-wave (CW) operation with a single-stage depressed collector and deposited beam power of about 20 kW is believed to be the first demonstration of its kind for a W-band gyro-TWT.
