Method and Apparatus For Generating Radiation or Particles By Interaction Between a Laser Beam and a Target

摘要

To generate radiation or particles by interaction between a laser beam and a target, the selected target is a free flow (5) in a vacuum enclosure (40) of a powder made up of solid grains of size from 10 μm to 1 mm and the laser beam (9), which is an intense pulsed laser beam, is focused onto the powder flow (5) that is driven by gravity only, to create an interaction area (8) generating the radiation or the particles in the vacuum enclosure (40), in which the internal pressure is less than 1000 Pa.
