REALTIME RADIATION EXPOSURE MONITOR AND CONTROL APPARATUS

Номер: CA1155562A
Автор: COWART RONALD W, COWART, RONALD W.
Принадлежит: UNIV TEXAS SYSTEM THE, UNIVERSITY OF TEXAS SYSTEM (THE)

An apparatus for measuring radiation exposure in realtime by measuring the charge flowing in an external circuit when radiation creates electron hole pairs, and thus allows discharge of a duo-dielectric detector. The apparatus comprises a radiation source adapted to irradiate a multi-layered detector structure, an external circuit connected to the transparent insulating layer and to a conductive layer of the multi-layered detector structure, and a device for measuring the flow of current through this external circuit when the multi-layered detector structure is irradiated. This exposure measuring apparatus is unique in that it measures the voltage of the output electric signal as a function of the surface charge present at the spot where the radiation source strikes the photoconductive layer of the detector.

METHOD OF IMPRESSING AND READING OUT A SURFACE CHARGE ON A MULTILAYERED DETECTOR STRUCTURE

A latent charge image is recorded on and reproduced from a multilayered detector by first providing the detector with a uniform surface charge on its photoconductive layer. The photoconductive layer is then biased with an electric field whose polarity opposes that of the uniform surface charge and then the detector is exposed to a modulated radiation flux to cause at least partial discharge of the photoconductive layer. The latent charge image of the modulated radiation flux is thus stored and later read by scanning the surface of the photoconductive layer with a small diameter photon beam to further sequentially discharge the photoconductive layer and the changing electrical potential of this sequential further discharge is detected and processed into a video signal by a processor for storage or display. The unique step of biasing the photoconductive layer with an electric field of opposite polarity to the surface charge greatly increases the efficiency of the detector, the detector's ...
