FIELD: electricity.
SUBSTANCE: gas-discharge device for processing heat-sensitive surfaces contains a discharge chamber (1) made of a dielectric material, a gas feed and control system (2), an axial electrode (3), which is threaded through the insulating tube (4) and is installed inside the discharge chamber (1) with the sealed holder (5), a grounded annular electrode (6) mounted on the cylindrical dielectric sleeve (7), which is inserted into the discharge chamber (1). When the AC voltage source (8) is connected through a current limiting resistor (9) and feedback resistor (10) to the discharge interval between the axial (3) and grounded circuit (6) electrodes, as well as connected to the modulator output voltage (11).
EFFECT: invention provides an efficient treatment of heat-sensitive surfaces by improving the stability of the discharge parameters, and a significant cost reduction due to the simplified construction of the device.
