HIGH-FREQUENCY GENERATOR BUILT AROUND HOLLOW ARC-CATHODE Russian patent published in 2008 - IPC H01J17/38 

FIELD: electrical engineering.

SUBSTANCE: invention relates to high-frequency hardware and can be used producing high-frequency radiation generators (HFG). The HFG built around the hollow arc-cathode incorporates a vacuum discharge chamber formed by the grounded hollow cathode with its open space facing the anode isolated from the cathode and closing the said open space, a blocking capacitor with its one plate connected in circuit via a transfer line formed by a forward conductor connecting the capacitor other plate to the load and a reverse conductor to couple the cathode with the load. To output the generated radiation, the said reverse conductor represents a conducting enclosure enveloping the cathode over its edges in contact with the former and housing the aforesaid blocking capacitor and the forward conductor. A coaxial cable with an inner conductor making a forward conductor and its sheath, making a reverse conductor, is formed by the conducting shell connected to the cable outer conductor and isolated from the inner conductor.

EFFECT: output of generated HF radiation with lower losses due to reduced inductance of power transfer line.
