Abstract
An unusually lightweight and readily portable X-ray machine is achieved through the use of a multi-stage DC voltage multiplier combined with a multi-stage AC filament current stepdown transformer, incorporating unique components and subassemblies. Multi-prong clamping inter-stage connectors couple diode strings to plural capacitor array junctions and to conductors matching interstage DC potentials between multiplier stages and transformer stages. A high voltage input transformer for the multiplier incorporates dual insulating layers, a relatively thick, heat-resistant Teflon layer exhibiting extremely low dielectric losses and a thinner Epoxy layer having a tractive outer surface supporting a large plurality of fine wire secondary winding turns. A laser target selector removably mountable on the X-ray tube's projection portal illuminates a target spot to allow adjusted aiming of the X-ray beam.
