Low-pressure high-power gas-discharge switch e.g. for pulsed high power laser, fusion and acceleration technology

摘要

A low-pressure gas discharge switch, with planar main electrodes for a generating a low-pressure gas discharge and spaced at least by distance d from one another, and which form a cathode, an anode, and a discharge gap or path in a switching chamber for a discharge plasma, the latter being triggered by increasing the electron density in a cathode cavity. At least the cathode has at least one opening for triggering the gas-discharge path, and a device is provided for generating a magnetic field which superposes the discharge plasma. At least one slot (100,200) is used in at least one of the planar main electrodes (1,2) as a device for generating a radial magnetic field.
