——对低电压、典型低噪声行波管内电子注的自发偏转进行了研究,并且认为是在上釉的螺旋线夹持杆上积聚了杂散电荷的缘故。叙述了对螺旋线上显示这些充电效应趋向进行测量的方法。讨论了防止电荷积聚,但又不严重影响其冷损耗或其他微波特性的整个螺旋线的处理方法。采用经此种工艺处理的螺旋线制成的行波管并不显示充电效应或电子注偏转。六只管子已累积了22,000管一小时,而无损坏。 - The spontaneous deflection of the electron injection in a low-voltage, typically low-noise traveling-wave tube has been studied and is believed to accumulate stray charges on the glazed helix clamp rod. Describes the method of measuring the tendency of these charging effects on a spiral. The treatment of the entire helix that prevents charge buildup but does not seriously affect its cold loss or other microwave characteristics is discussed. Traveling wave tubes made of helixes treated by this kind of process do not show charge effects or electron beam deflection. Six tubes have accumulated 22,000 tubes an hour without damage.
