Abstract:
Provided is a compact device which captures, over a large solid angle range, electrically charged particles emitted from a point source and parallelizes the trajectories of said charged particles. The present invention is configured from: an electrostatic lens comprising a plurality of axisymmetric electrodes ( 10 - 14 ) and an axisymmetric aspherical mesh ( 2 ) which has a surface that is concave away from the point source; and a flat collimator plate ( 3 ) positioned coaxially with the electrostatic lens. The acceptance angle for the electrically charged particles generated from a point source ( 7 ) is ±30° or greater. The shape of the aspherical mesh ( 2 ), and the potentials and the positions of a ground electrode ( 10 ) and application electrodes ( 11 - 15 ) are adjusted so that the trajectories of the electrically charged particles are substantially parallelized by the electrostatic lens. The electrostatic lens and the flat collimator plate are positioned on a common axis.

Claim (Index 12):
An angle distribution measurement and analysis apparatus as set forth in  claim 11 , further comprising:\n a retarding-voltage plane grid for preforming lock-in detection of change in current by charged particles passing through said grid by changing DC voltage being applied to said grid, being further provided, and charged particles of specific kinetic energy emitted from said planar collimator plate being detected.
