Title:
DEVICE FOR DETECTING PROPAGATION ENERGY
Document Type and Number:
Japanese Patent JPS62162984
Kind Code:
A
Abstract:
An apparatus for detecting propogating energy in a defined space includes a medium disposed within the space which interacts with the incident propogating energy to produce secondary energy. An electrostatic field is impressed across the defined space for directing the secondary energy toward a planar detector located at one end of the space. Adjacent the detector is positioned a planar grid for preventing the secondary energy from being detected by the detector prior to passage through the grid. The grid comprises a three layer device having a middle layer formed of an electrically insulative sheet material of a relatively stiff structure. The other two layers comprise conductive layers on opposed surfaces of the first layer which are connected to an electric potential for creating a field across the grid structure and a further field between the grid structure and the detector for accelerating the secondary energy toward the detector in the area of the grid at a space between the grid and detector.
