Preliminary study positive and negative polarity pseudo-spark switches
This paper introduces a pseudo-spark switch which works in positive and negative polarity and does not need hot wire power supply. It can be triggered by one of the three modes of electric triggering, space light and fiber transmission laser energy. In the electric trigger mode, the technical specifications of the switch reach the operating voltage ±60 kV, the pulse current16.2 kA and the close jitter 7 ns; In space light trigger mode, the close jitter is 3 ns using 1 mJ/532 nm laser, and the minimum triggering laser energy is 0.15 mJ. In the fiber transmission laser energy mode (the energy of the incident end of the fiber is 7 mJ/the output end is 5 mJ), the close jitter is 3 ns.
