Author Rémi Longtin    Category Publications     Tags ,

Scientists at the Swiss Federal Laboratories for Materials Science and Technology in Zurich, Switzerland, have built a functional X-ray tube using carbon nanotubes as electron sources. Carbon nanotube electron field-emission is well known effect and has been studied since the mid 1990s. Since then, several X-ray sources have been described in the scientific and technical literature.
