High Rotational Speeds in Vacuum

Review of Scientific Instruments, 1941
Rotors freely suspended in high vacuum were driven to high rotational speeds by electrostatic and by electromagnetic forces. The first suspension used was a modification of the photoelectrically stabilized suspension developed in this laboratory by F. T. Holmes. Another magnetic suspension was developed which was stabilized by capacity coupling.
