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 pof inert gas is set so that inequality p<p<10-10Torr is met, where pis 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, where Pis 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.5 dwg |
