WebOf the conventionally used fast atom beam sources that generate fast atom beams of gas atoms, the kinetic energy is An example of a fast atom beam source that emits argon atoms of 0.5 to 10 keV is shown in FIG. In the figure, reference numeral 1 is a … WebA fast atom beam source which is capable of efficiently emitting a fast atom beam with low energy and high particle flux. A plate-shaped electrode (21) has a multiplicity of atom emitting holes (7). A pair of electrodes (22 and 28) are disposed in series to face opposite to the plate-shaped electrode so as to form an electric discharge part.
Webleaving a beam of fast-moving atoms that exits from the gun. The beam is somewhat divergent, so the gun is situated near the target. Instead of the fast-atom beam, a primary ion-beam gun can be used in just the same way. Generally, such an ion gun emits a stream of cesium ions (Cs"), which are cheaper to use than xenon but still Web2 days ago · It’ll then drop at BEAMS Harajuku on April 22.
