Abstract: An apparatus for manipulating the trajectories of moving charged particles. The apparatus includes a grid of laterally spaced side by side elongate elements and means defining a path for charged particles to traverse the grid. The grid is supported and configured for application of a voltage gradient between and/or along the elongate elements, whereby to manipulate the trajectories of charged particles that traverse the grid. A method of manipulating the trajectories of moving charged particles is also disclosed.

Abstract: Electron focussing apparatus includes a cathode plate defining an impact surface on which particles impact, which surface has a finite probability of generating at least one electron for each impacting particle having predetermined characteristics. The apparatus also has an electron receiving element, and respective means for generating electrostatic and magnetic fields in a space extending from the impact surface to the electron receiving element. The means for generating the electrostatic and magnetic fields are configured whereby the E/B2 ratio adjacent the electron receiving element is smaller than adjacent the impact surface, whereby to decrease the radius of curvature of the electron trajectories adjacent the electron receiving element relative to adjacent the impact surface and to thereby focus the electron trajectories in at least one dimension. In another aspect the electron receiving element is positioned and the means for generating the electrostatic and magnetic fields are configured to cause the electrons to deflect on average through greater than 180° before impacting the electron receiving element, whereby to focus, in at least one dimension, multiple electrons generated from any given area of the impact surface to a smaller area at the electron receiving element.

Abstract: An electron multiplier detector includes cathode structure defining a plurality of spaced co-planar impact surface segments on which particles impact. These surface segments each have a finite probability of generating at least one electron for each impacting particle having predetermined characteristics. The detector further includes respective sets of electron multiplication dynode segments associated with the impact surface segments, the sets being arranged as substantially parallel arrays extending behind the impact surface segments, and respective means for generating electrostatic and magnetic fields in a space extending from the impact surface segments past the dynode segments, whereby respective streams of electrons cascade and multiply successively along the arrays of dynode segments. Collector structure is provided to receive and detect the streams of electrons downstream of the last dynode segments in the arrays.
