Abstract:
1. A virtual Frisch-grid detector array comprising an internal module surrounded by an edge module, wherein each module comprises a plurality of virtual Frisch-grid detectors and said virtual Frisch-grid detectors comprise a semiconductor capable of operating as a single-carrier-transport device having a first surface and a second surface, an anode connected to the first surface of the semiconductor, a cathode connected to the second surface of the semiconductor, and a shielding electrode producing the virtual Frisch-grid effect spanning the perimeter of the semiconductor between the first surface and the second surface; wherein the virtual Frisch-detectors in the internal module have the shielding electrode extending a partial length of a semiconductor from the edge of the anode, and the virtual Frisch-detectors in the edge module have the shielding electrode extending a full length of a semiconductor.
