Scientists have reached another milestone in developing a promising technology for accelerating particles to high energies in short distances: They created a tiny tube of hot, ionized gas, or plasma, ...

Fujitsu Laboratories Ltd. has been developing a revolutionary new plasma tube technology to produce narrow glass tubes, measuring one meter in length and one-millimeter in diameter, that emit light ...

The device works by ionizing air to create a low-temperature plasma, which is blown up a tube by an air compressor. Part way up the tube, the plasma is hit with a powerful microwave, which shakes the ...
