Successful suppression of pulse-shortening in an X-band overmoded Relativistic Backward Wave Oscillator with Pure TM01 Mode Output

by Jun Zhang, Zhenxing Jin, Jianhua Yang, Dian Zhang, Ting Shu, Jiande Zhang, and Huihuang Zhong


Long-pulse operation of relativistic backward-wave oscillators (RBWOs) is seriously handicapped by pulse-shortening phenomenon. Explosive emission plasma formed on the surface of slow-wave structures (SWSs) due to RF breakdown is considered to be the predominant cause of pulse shortening in RBWOs. Utilizing overmoded SWSs with large diameter is effective for decreasing the field strength on the surface of SWSs and the possibility of RF breakdown. However, multiple modes may be output simultaneously in overmoded RBWOs. more...

Influencing Factors of Dielectric Breakdown in the PEF Treatment Chamber

by Ruobing Zhang, Nanchen Zheng, Huaiyu Liu, and Liming Wang


Electrical breakdown of the treatment chambers under repetitive high-intensity pulses impedes the industrial application of pulsed electric field (PEF) technology. In this paper, phenomenon and laws of electric discharges in the PEF treatment chambers were studied. The experimental results indicate that temperature increase and formation of gas bubbles under high electric field strength reduces insulation of water solution. Air dissolved in the samples is only a small part of the bubble and hardly affects the size of bubble formed. more...
