ELECTROSTATIC ENERGY ANALYSER FOR PARALLEL STREAM OF CHARGED PARTICLES Russian patent published in 2008 - IPC H01J49/48 

FIELD: physics.

SUBSTANCE: invention pertains to the spectroscopy of streams of charged particles and can be used when making electrostatic energy analysers with high resolution power for energy, high sensitivity, simple structure and economical investigation streams of charged particles in space or plasma. The electrostatic energy analyser consists of inner and outer cylindrical coaxial electrodes, a flat limiting electrode, perpendicular axis of symmetry, with potential of the inner cylindrical electrode, with an output window in it, made in the inner cylindrical electrode, receiver diaphragm and detector, located outside the field in the cavity of the inner cylindrical electrode. The stream of charged particles is directed parallel the axis of symmetry of the cylindrical electrodes and is behind the output window of the limiting flat electrode, perpendicular to the axis of symmetry, at the potential of the inner cylindrical electrode.

EFFECT: increased sensitivity and resolution power of the analyser.
