ELECTRONIC MAGNETIC SPECTROMETER

摘要

The invention relates to the testing and analysis of materials by radiation methods and can be used for diagnosticating the structure and the composition of the surface and near-surface layers of solid and liquid bodies. The aim of said invention is to simplify a device structural design, to reduce the overall dimensions, mass and cost thereof and to extend the functionalities of the device. The inventive electronic magnetic spectrometer comprises a vacuum chamber, an energy analyser in the form of circular electric circuits, a slit-shaped aperture and an electrons detector, wherein the electric circuits of the energy analyser are embodied in such a way that they make it possible to form, in the vacuum chamber, a magnetic field dependent on the radius ? of the electron orbit according to a formula H~?-a, wherein H is magnetic field strength and a=0.62-0.76. In addition, the slit-shaped aperture and the electrons detector are embodied in such a way that they are enabled to be displaceable in the cross-section plane of the energy analyser and to be secured in a specified position.
