  • Monochromator for charged particles
    Patent number: 4412131
    Abstract: A monochromator for charged particles comprises a premonochromator and a main monochromator is tandem with a retarding lens disposed therebetween. The arrangement is suitable for electron energy loss spectrometry due to the high achievable intensities.
    Type: Grant

  • Beam guidance for electron beam tests, and electron impact spectrometer having such beam guidance
    Patent number: 4300045
    Abstract: A beam guidance for electron beam tests, especially of solid bodies. The ctrons cathodically emitted and electron-optically bundled are subjected at least to an energy selection in a cylinder condenser deflection unit and are subsequently detected or indicated in a detector. The emission and bundling systems are arranged in such a way that the electrons, in the plane at right angles to the cylinder condenser axis, are focused upon the inlet shield or baffle of the condenser, yet are focused at right angles thereto upon the detector.

  • Electronic or ionic optical apparatus
    Patent number: 4270053
    Abstract: Electronic or ionic optical apparatus having baffled wall areas wherein the individual baffles are constructed and positioned such that a maximum probability is created for particles departing from the desired paths through the apparatus to pass through the baffles. A chamber is preferably provided behind the baffled wall areas which is closed off except for the openings between the individual baffles.
