Abstract

1,145,108. Particle spectrometers. APPLIED RESEARCH LABORATORIES Inc. 4 Oct., 1966 [11 Oct., 1965], No. 34418/68. Divided out of 1,145,108. Heading H1D. A particle dispensing sector lens such as an electric, spherically curved, toroidal condenser 12, is associated with an electric unipotential lens 10 to reduce the distance between the object and image planes and so increase the acceptance angle at the aperture diaphragm 40. The unipotential lens 10 comprises electrodes 34, 36, 38 and a set of deflection plates 32 is provided to adjust the direction and position of the particle beam. In another system a magnetic sector lens is associated with a unipotential lens on each side of the sector lens along the particle beam axis.
