Analyzer of the energy of the beams of particles loaded spherical a discretization

摘要

The invention relates to an analyzer of the energy of the charged particle beams of the spherical type in reflection, which comprises a source of a beam of charged particles, two electrodes which are concentric spherical in shape, connected to a voltage source, in which the inner electrode has windows for the passage of the beam of charged particles, as well as a reception device. / p & & p & according to the invention, the source 4 of the beam of charged particles and the device 5 for receiving the form of segments of a sphere, they are disposed symmetrically to one another with respect to the center of the spheres and at least one of them is disposed at the inner spherical surface of the electrode 1. / p & & p & in particular, the invention applies to the creation of new electronic spectrometers for the analysis of solid bodies by methods of spectroscopy to scan.
