Examples
- The experimental results show : the flattop phenomenon on the diode voltage pulse was very apparent for using the carbon fiber cathode , that is to say , the pulse duration of the diode voltage was widened ; moreover , under the condition of the same power of microwave , the pulse duration of the out - put microwave was prolonged by about 30 % ; the peak power of the microwave was enhanced by 3db
通过在装置上做的两种阴极的对比实验,结果显示:碳纤维阴极的使用,改善了电子束质量,使辐射微波的脉宽增加了30 %以上,辐射主瓣方向上的功率密度提高了3db以上,频谱分布较纯净,实现了微波的高效输出。
