Title: Electronically shielded solid state charged particle detector

Abstract

An electronically shielded solid state charged particle detector system having enhanced radio frequency interference immunity includes a detector housing with a detector entrance opening for receiving the charged particles. A charged particle detector having an active surface is disposed within the housing. The active surface faces toward the detector entrance opening for providing electrical signals representative of the received charged particles when the received charged particles are applied to the active surface. A conductive layer is disposed upon the active surface. In a preferred embodiment, a nonconductive layer is disposed between the conductive layer and the active surface. The conductive layer is electrically coupled to the detector housing to provide a substantially continuous conductive electrical shield surrounding the active surface. The inner surface of the detector housing is supplemented with a radio frequency absorbing material such as ferrite. 1 fig.

  • A method for controlling the population inversion in a solid state laser material is described. The method consists of optically pumping the material with a laser beam having a wavelength corresponding to the absorption band of the laser material and the output of which is spatially and temperally modulated. Spatial and temporal modulations of the population inversion in the pumped material are achieved by means of a two-dimensional spatial modulator positioned between the pump laser beam and the pumped laser material, the modulation being thermooptically controlled by a scanning electron or laser beam or electro-optically controlled by a scanning electronmore » beam or acousto-optically controlled by a two-dimensional acousto-optical modulator. Utilization of a lens between the spatial modulator and the optical cavity of the laser material permits electronic deflection of the output from said laser material by focusing the beam transmitted through said spatial modulator.« less
