Microwave Tubes / Power Grid Tubes
Gyrotrons
Canon 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 Canon 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, Canon 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
