About the RS 3020CJ
The RS 3020CJ is a power triode manufactured by Thomson / Thales. Thales RS 3020CJ water-cooled metal-ceramic triode for high-power RF end stage in industrial CO₂ laser and RF heating applications.
Key ratings of the RS 3020CJ include tube type Triode, construction Metal-ceramic, anode cooling Water and cathode Thorium tungsten.
Typical applications are industrial RF end stage, CO₂ laser machines, RF heating systems and industrial RF generators. Notable features: RS 3020 water-cooled triode, metal-ceramic construction, water-cooled anode and industrial duty.
Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
