Abstract
A capacitor is described which has been used to make accurate measurements of the dielectric constant of liquid and gaseous oxygen over a wide temperature (55–300 K) and pressure (0.2–34 MN/m2) range. The capacitor is simple to construct and its stability is unaffected by large hydrostatic pressure variations. The temperature variation of the vacuum capacitance is small and remains reproducible even after repeated temperature and pressure cycling.Keywords
