Abstract

Abstract

To investigate the problem of breakdown between the adjacent turns of the helix pulse forming line (PFL), the influences on the axial electric field of the helix PFL were analyzed numerically. Numerical results indicated that it was easier to breakdown between the adjacent turns if the helix angle was bigger, the rise time of the switch or the load value was smaller. To study the problem of the upshot and hollow on the output pulse, the influences on the waveform caused by the impedance mismatched sections in helix PFL accelerator were analyzed numerically and experimentally. An approximate square high voltage pulse was obtained by making the impedances of the joint section (between the helix line and switch) and the transition section (between switch and load) close to that of the helix l
