FIELD: electrovacuum technology. SUBSTANCE: method involves evacuation, degassing of gas absorber during evacuation, cathode activation, and electric sealing. Gas absorber is degassed in cycles with gas absorber temperature being maintained at desired value and residual gas pressure in system checked; heating and vent gas evacuation cycle time is set according to residual gas pressure equal to P ≅ 2,0·10-2 mm Hg. EFFECT: facilitated procedure. 1 dwg
