FIELD: measuring equipment.
SUBSTANCE: glow discharge is excited in the laser gyroscope and the emission spectrum is recorded. Then the discharge is quenched and a sealed cap is subsequently installed on the gyroscope details, connected to the housing either by the method of an optical contact or through an indium seal. The indicator gas is supplied under the cap and maintained with excessive pressure for a predetermined time. After each setting and holding in the laser gyroscope, a glow discharge is again excited and the appearance of the spectral line of the indicator gas in the emission spectrum is recorded. The appearance of the spectral line of the indicator gas or the increase of its intensity indicates that the connection of this detail with the housing is leaking.
EFFECT: ensuring the possibility of unambiguous localization of the source of leakiness.
