An A & D team based at the Graduate School of Engineering, Nagoya Institute of Technology, led by Professor Fumio Okuyama, has developed an X-ray tube operated with a carbon nanotube electron beam.
The X-ray tube has been developed on the observation that the carbon nanotube is an electric field electron beam emitter, and represents an X-ray tube that is not based on hot electron emission.
It can be fabricated in an ultra compact size for insertion into an endoscope enabling the commercialisation of X-ray tubes which are applicable to the pin point imaging of diseased organs,
This carbon nanotube is an ultrafine hollow carbon fibre with an external size of 'less ...
