摘　　要：设计了基于低阻形成线对非匹配传输线充电型宽谱振荡器,介绍了振荡器的工作原理。在数值模拟分析的基础上,完成了低阻形成线、非匹配传输线的结构设计。此宽谱振荡器在1 MV Marx实验平台上开展了实验研究,在主开关的间隙为14mm、气压1.5MPa,短路开关间隙为6mm、气压1.0MPa,锐化开关间隙为4mm、气压1.1 MPa的条件下,实现了宽谱脉冲重复频率20 Hz稳定输出,中心频率达到260 MHz。采用低阻形成线对非匹配传输线充电技术,既实现了高功率宽谱振荡脉冲又提高了脉冲的中心频率。The paper presents a high power wide band oscillator with nonmatched transmission line which is charged by low impedance forming line.The designs of low impedance forming line and nonmatched transmission line are completed accordingly and high voltage experiments are conducted on the 1 MV Marx generation.The wide band oscillator can output wide-spectrum pulse with center frequency 260 MHz,repeat rate 20 Hz when the gap of main switch is 14 mm with 1.5 MPa SF 6,the gap of chopping switch is 6 mm with 1.0 MPa SF 6,and the gap of peaking switch is 4 mm with 1.1 MPa SF 6.The technology of nonmatched transmission line charged by low impedance forming line can output high power wide band pulse and increase center frequency.
