Dielectric strength of liquid helium in millimeter gaps
Abstract
A program underway at Oak Ridge National Laboratory to investigate the high voltage electrical properties of fluids and solids for cryogenic systems is described. As the first result of these investigations, measurements of the breakdown strength of liquid helium boiling at atmospheric pressure, under voltages up to + or - 130 kV dc and in gaps of up to 2.5 mm, are reported. Preliminary results with ac voltage were also obtained.
