Abstract
A new type of low-pressure gas switch is described. The switch is triggered by an electron beam that is emitted from the surface of a ferroelectric sample. The electron beam is generated within the hollow cathode and ejected through a hole of arbitrary shape into the main gap of the switch. The beam current and the electron energy can be chosen such that breakdown is achieved with small jitter. The switch with its ferroelectric trigger requires neither heating nor an auxiliary gas discharge. The fast spontaneous polarization change ΔPs, which is the cause of electron emission, is induced by a high-voltage pulse from an electronic switching circuit.Keywords
