METHOD FOR RECOVERY OF POWERFUL VACUUM SHF-DEVICE OF GYROTRON TYPE Russian patent published in 2015 - IPC H01J9/04 

FIELD: electricity.

SUBSTANCE: method includes cathode processing by ion flow and control of emission current measurement at cathode in process of ion-beam processing. Gyrotron is equipped with inert gas puffing and degassing systems, pressure p_i of inert gas is set so that inequality p_min<p_i<10^-5-10^-4 Torr is met, where p_min is minimum pressure of inert gas, at that required time of ion-beam processing has maximum value, filament voltage is supplied to cathode and filament power is set as P≤P_s, where P_s is standard cathode glow, anode voltage is connected and its values is set, ionic processing is made at selected anode voltage and switched on magnetic field.

EFFECT: simplifying the recovery method and expanding its scope of application.
