About the CTK 24-5

The CTK 24-5 is a power triode manufactured by Thomson / Thales. Thales coaxial metal-ceramic power triode bridging the CTK 15-2 and CTK 25-4 power levels for industrial RF and CO₂ laser applications.

Key ratings of the CTK 24-5 include tube type Triode, construction Metal-ceramic coaxial, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.

Typical applications are CO₂ laser cutting oscillators, industrial RF heating, RF power amplifiers, plastic welding and induction heating systems. Notable features: intermediate CTK series power, metal-ceramic coaxial design, water-cooled anode and high-µ triode.

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.
