METHOD FOR DEVICE EVACUATION AND FILLING IT WITH GAS Russian patent published in 2002 - IPC

FIELD: electrical engineering; manufacture of gas-filled devices. SUBSTANCE: method used for evacuating hydrogen thyratrons, plasma- beam microwave devices, gyroscopes, and lasers and filling them with gas includes evacuation and warming up of device incorporating a number of gas absorbers, its filling with gas ,and encapsulation; novelty is that in the beginning of these procedures steady gas flow is set up in evacuation system corresponding to steady state gas pressure P_s within device, evacuation and warming up procedures are conducted until steady state pressure P_s is attained within device, and then the latter is encapsulated, steady state pressure P_s and gas absorber temperature being chosen so as to set up thermodynamic absorber-gas equilibrium within device at desired gas concentrations in gas absorbers or desired total amount of gas absorbed within device. EFFECT: reduced labor consumption for device evacuation and filling with gas at large amount of gas introduced. 3 cl, 1 dwg
