FIELD: vacuum switches, accelerators, and other high-voltage devices.
SUBSTANCE: proposed method for enhancing electric strength of high-voltage vacuum gaps involves introduction of gaseous-state molecules of high polarizing ability in vacuum gap to form dynamically stable monomolecular films preventing unwanted field-effect emission on surface irregularities (such as microscopic points) of electrodes. Molecule source is sublimation of solid material in vacuum gap.
EFFECT: facilitated procedure and enhanced life of protective film.
