Title: Long-distance transmission of light in a scintillator-based radiation detector

Abstract

Scintillator-based radiation detectors capable of transmitting light indicating the presence of radiation for long distances are disclosed herein. A radiation detector can include a scintillator layer and a light-guide layer. The scintillator layer is configured to produce light upon receiving incident radiation. The light-guide layer is configured to receive light produced by the scintillator layer and either propagate the received light through the radiation detector or absorb the received light and emit light, through fluorescence, that is propagated through the radiation detector. A radiation detector can also include an outer layer partially surrounding the scintillator layer and light-guide layer. The index of refraction of the light-guide layer can be greater than the index of refraction of adjacent layers.

  • A radiation detector system used in aerial dosimetry in which an inorganic scintillation crystal detector and spectral filter are coupled to a photomultiplier tube and the requisite electronic circuits is described. The crystal detector is pointed toward an area to be monitored for x-ray or gamma ray and the resulting optical radiation therefrom is applied to the photomultiplier tube for converting to an electrical output therefrom which is monitored to indicate the radiation dosage.

  • A high speed serial data transmission multiplexing circuit, which is operable to accurately transmit data over long distances (up to 3 Km), and to multiplex, select and continuously display real time analog signals in a bandwidth from DC to 100 Khz. The circuit is made fault tolerant by use of a programmable flywheel algorithm, which enables the circuit to tolerate one transmission error before losing synchronization of the transmitted frames of data. A method of encoding and framing captured and transmitted data is used which has a low overhead and prevents some particular transmitted data patterns from locking an includedmore » detector/decoder circuit.« less
