Gyrotrons

Gyrotrons

Toshiba Electron Tubes & Devices has engaged in the development of gyrotrons as an RF source for fusion plasma heating and measurement for many years.

Japan Atomic Energy Agency and Toshiba Electron Tubes & Devices have developed three key technologies for high-power quasi-CW gyrotrons: a depressed collector, a higher-order mode cavity, and a CVD diamond window. We have achieved short pulses (one millisecond) at 1.3 MW, and power levels of one megawatt for around ten seconds.

Moreover, Toshiba Electron Tubes & Devices was the first company to succeed in improving efficiency from 30% to 50% by collecting energy from the electron beam (collector fall-of-potential)


Features

  • High efficiency
  • Realizes more compact, low cost, and energy saving power supply and cooling units
  • Decreases undesirable X-rays
  • Improved high-power performance thanks to planarization of the output distribution
  • 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

  • Plasma heating in experimental nuclear fusion apparatus
  • Plasma measurement in experimental nuclear fusion apparatus
  • Ceramic sintering
