METHOD FOR MANUFACTURING GAS DISCHARGING CHAMBER FOR GAS DISCHARGING HIGH-FREQUENCY PULSES GENERATOR WITH A SET CARRIER GENERATION FREQUENCY Russian patent published in 2023 - IPC H01J17/38 H01J9/02 

FIELD: radio frequency engineering.

SUBSTANCE: invention can be used in the development and creation of high-power pulse generators in the high-frequency (HF) range. A method for manufacturing a gas-discharge chamber for a gas-discharge generator of high-frequency pulses with a set carrier frequency of generation, in which a gas-discharge chamber is manufactured for initiating high-current gas discharges with a hollow cathode at low pressure, moreover, a cavity is provided in the cathode of the chamber, open towards the anode; the geometric parameters of the cavity are selected arbitrarily and taken as a standard; a high-frequency pulse generator is mounted on the basis of a gas-discharge chamber containing a cathode with a reference cavity, and the carrier frequency of the pulse generation of this generator is experimentally measured; calculate the effective area by the formula S_eff = S_ref⋅ (ƒ_ref/ƒ_set)⁴, where S_ref is the surface area of the reference cavity, ƒ_ref is the carrier frequency of the generation of pulses generated by a chamber containing a cathode with a reference cavity, ƒ_set is the specified carrier frequency at which it is required to provide RF generation; make a cathode with a cavity, the surface area of which is equal to the effective value of S_eff, otherwise the form factor of the manufactured cathode with an effective cavity corresponds to the form factor of the cathode with a reference cavity; a cathode with an effective cathode cavity is mounted in a gas-discharge chamber, while manufacturing a gas-discharge chamber for a gas-discharge generator of high-frequency pulses with a given carrier frequency of generation.

EFFECT: increased accuracy of providing the specified value of the carrier frequency of the generation of a gas-discharge HF-generator based on a gas-discharge chamber without conducting a large number of experiments.
