Cascade rectifier power supply furnishes open-circuit voltage of 450 kv

A 450-kv power supply for powering and testing high-voltage switch tubes has been designed and constructed by Radiation at Stanford under U. S. Army Signal Corps sponsorship. The supply (shown on the front cover of this issue) is part of a complete facility for high-potential testing, high-voltage processing, and pulse-testing of high-voltage switch tubes and other components. The equipment, when used with a switch tube and floating deck modulator, also can be operated as an inexpensive, low-duty modulator for testing high-power transmitting tubes.
