Abstract:
This paper presents a high power no matching transmission line based on chopping-peaking switch,and studies its operating principles. The effects of the switch break-over time, the switch break-over time-delay and the length of the no matching transm...

Abstract:
The design of the linear transformer driver(LTD) stage prototype for Z-pinch driver is introduced. The stage consists of 32 identical bricks connected in parallel. Each brick contains two 100 kV/100 nF capacitors, a 200 kV multi-gap switch, and the o...

Abstract:
For accelerator driven sub-critical system (ADS) injector Ⅱ, we studied its fast protection system and timing system, and designed a PXIe controller which could be used to construct fast protection system and timing system. The PXIe controller could ...

Abstract:
In this paper, we demonstrate the exclusive display of the patterns fabricated by femtosecond laser with a central wavelength of 800 nm on the 316L stainless steel surface. The uniform ripple structures with a period of 540 nm can be produced under t...

Abstract:
Based on the lumped circuit model, the influences of parasitic elements of pulse transformer, turns ratio and impedance of load on the rise time and overshoot of output waveforms are discussed. The relationship of the parasitic elements between the s...
