Abstract
Abstract A high voltage accelerator power supply for providing a substantial current flow at a high D.C. voltage level including a step-up transformer mounted on an upright insulating frame at an intermediate level approximately midway between bottom and top of the power supply with the transformer being horizontally positioned and corona rings encircling the upper and lower edges of its core. One capacitor is below the level of the transformer core and another is above that level in a voltage-doubling arrangement while the core is electrically connected to a junction intermediate the two capacitors to be at an intermediate voltage level. A modular, flexible snake-like electrical device containing a plurality of series-connected rectifier cartridges positioned end-to-end, or similar components, enclosed within a plastic sheath enables connection with substantially uniform voltage stress distribution between a low voltage and a high voltage terminal by conveniently arranging the device in a helical or snake-like path. An isolation transformer system includes first and second widely separated cores one at ground potential and the other at the high D.C. output voltage of the supply, with an endless loop coupling winding at intermediate D.C. level and encased in a heavy insulation covering wound a few turns on each core.
