In collaboration with various research
institutes, in particular Japan Atomic Energy Research
Institute, Toshiba has improved its technological
capabilities, and seen lots of results from these
efforts. Among them, we created integrated mode converter
technology, and we are hoping to break through the
limits of high-power performance using this technology.
The integrated mode converter directs the output power
at a right angle to axis of the tube, then the collector,
which transforms used-out electron beams to heat,
is released from the constraint as an output waveguide.
By taking advantage of the integral converter, Toshiba
has achieved a significant improvement in conversion
efficiency by collecting the energy from the used-out
electron beams (CPD: Collector Potential Depression).
Our Gyrotron was the first tube of this type in the
world, in 1994. This improvement dramatically increased
the efficiency to about 50% from the previous level
of about 30%. |
 Features
- Employs a small collector thanks to the high efficiency of the
Gyrotron.
- Creates a compact, low cost, and energy saving power supply
unit and cooling unit, thanks to the high efficiency performance
of the Gyrotron.
- Decreases undesirable X rays.
- Improved high-power performance, thanks to a uniform output
distribution.
- Toshiba's unique long life and high-current-density cathodes.
- High reliability, based on advanced high-vacuum, and high-voltage
technologies created in the development of various type of electron
tubes.
