PULSE COLD CATHODE Russian patent published in 1994 - IPC

FIELD: electron-ion accelerating equipment. SUBSTANCE: pulse cold cathode with outer cylindrical ceramic working surface has dielectric plasma-forming element in the form of cylindrical ceramic tube with working surface. Ceramic tube is mounted for rotation in metal holder anchored on base of cathode. Main pectinate metal electrode is fastened on support of holder. Its teeth have restoring mechanical contact with ceramic working surface of cathode. Cathode is placed in air-evacuated space of body of electron accelerator with outlet window. Base of cathode is connected to negative and body - to positive lead of pulse power supply source. EFFECT: improved efficiency in generation of charged particles. 11 cl, 10 dwg
