An electrostatically-suspended spinning-rotor vacuum gauge: a feasibility study

A comparison is made between the magnetically-suspended spinning-rotor vacuum gauge and the electrostatically-suspended gyroscope, both of which, for different purposes, employ spinning balls suspended in vavuum. It is suggested that an electrostatic suspension might usefully extend the practical me...

Summary:A comparison is made between the magnetically-suspended spinning-rotor vacuum gauge and the electrostatically-suspended gyroscope, both of which, for different purposes, employ spinning balls suspended in vavuum. It is suggested that an electrostatic suspension might usefully extend the practical measurement range of the vacuum gauge, and a design study is presented.
