Title:
GAS SWITCH TRIGGERED BY OPTICAL PULSE INTRODUCED BY OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2019/223407
Kind Code:
A1
Abstract:
Provided is a gas switch triggered by an optical pulse introduced by an optical fiber, which solves the problem of the existing electrically-triggered gas switch and laser-triggered gas switch having a complicated trigger system, being insufficiently reliable and having a higher cost due to the pulse amplitude/laser beam energy having higher requirements. The gas switch triggered by an optical pulse introduced by an optical fiber contains at least one trigger gap and one self-breakdown gap, wherein each trigger gap is connected to a photoconductive semiconductor switch in parallel, and an optical fiber is correspondingly configured to introduce an optical pulse for triggering. In the present invention, the advantages of a low trigger requirement of a photoconductive semiconductor switch and a high voltage and large flow of a gas switch are fully utilized, and an optical pulse introduced by an optical fiber is used to trigger the photoconductive semiconductor switch, so that the gas switch can be controlled and triggered under the action of a low-energy optical pulse (which can be less than 200 μJ) transmitted by the optical fiber, thereby greatly simplifying the scale and complexity of a trigger system and promoting the development and application of pulse power source technology.
