Crossed-Field Closing switch Development.
Abstract
The function of the crossed-field closing switch has been studied over a wide range of variables. It appears that the switch behavior is more complicated than originally expected. Three different modes of conduction have been observed: the conventional crossed-field discharge, a hybrid hollow-cathode discharge, and vacuum arcs. Depending on the amplitude and duration of the current, conduction may typically pass through these modes in the above sequence. The crossed-field closing switch may be triggered magnetically or by grid control into a number of states with varying levels of voltage drop. Conduction may be allowed in the reverse direction or prevented. The present design is limited in response speed and repetition rate by the inductance of the grid and anode leads, the lack of efficient pressure control, and the need for a pulsed magnetic field.
