Abstract
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.

A method of generating radiation or particles by interaction between a laser beam and a target, which method is characterized in that the selected target is a free flow in a vacuum enclosure of a powder made up of solid grains of size from 10 μm to 1 mm and the laser beam, which is an intense pulsed laser beam, is focused onto the powder flow that is driven by gravity only, to create an interaction area generating the radiation or the particles in the vacuum enclosure, in which the internal pressure is less than 1000 Pa.
A device for generating radiation or particles by interaction between a laser beam and a target, which device is characterized in that it comprises:
- a vacuum enclosure;
- a device inside the vacuum enclosure for creating a free flow of powder with solid grains of size from 10 μm to 1 mm;
- a laser source for emitting an intense pulsed laser beam;
- and
- focusing means for focusing the intense pulsed laser beam onto an area of interaction with the free flow of powder.
A device according to claim 27, characterized in that the connection between the feeder means and the feeder funnel is removable.
