Abstract
Abstract A multi-stage cascade voltage-multiplier device which includes electric condensers and diodes of the composite type comprising an assembly of elementary diodes. Each of the composite diodes is disposed between two conductive surfaces and is oriented substantially perpendicular to the surfaces at an adequate distance therefrom such that all of the elementary diodes are subjected to substantially the same instantaneous reverse voltage and undue breakdown of the diodes is prevented. In some embodiments the voltage-multiplier device is of the parallelseries type and is associated with a direct-current high-tension generator with at least the multiplier device incorporated in the barrel of an electrostatic projection gun.
