Microwave Tubes / Power Grid Tubes

Klystrons

Canon Electron Tubes & Devices is a world-leading manufacturer of klystrons. Through joint development with Japanese and international research institutes, Canon Electron Tubes & Devices has developed some of the world's most powerful klystrons such as the 508 MHz/1.2 MW continuous wave tube, the 2.8 GHz/100 MW pulsed tube, the 5.7 GHz/50 MW pulsed tube, and the 11.4 GHz/50 MW pulsed tube.

Furthermore, Canon Electron Tubes & Devices uses the latest technology to actively promote development of PPM (periodic permanent magnet) klystrons and multi-beam klystrons.

Klystrons

Features

  • High efficiency and high gain
  • High power performance realized by a multipactor discharge-suppressing titanium nitride coating on the output window
  • Uses our unique, long-life, high current density cathodes
  • Outstanding reliability realized through use of advanced high-vacuum and high-voltage technologies derived from the development of various types of electron tubes

Applications

  • High energy accelerators/Medical accelerators
  • Experimental nuclear fusion research facilities
  • Medical accelerators
  • Air traffic control radars
  • Airport ground control radars
  • Industrial microwave heating equipment
