High-flux anti-electromagnetic interference proton energy spectrum and intensity detector

Abstract

The invention belongs to the technical field of physical experiment radiation detection, and particularly relates to a high-flux anti-electromagnetic interference proton energy spectrum and intensitydetector. The detector comprises a scintillator, an optical fiber coupling cone, a transmission optical fiber, an optical fiber splitter, a gated photomultiplier, a digitizer and a data storage system. The physical process is as follows: high-flux ions bombard a scintillator to generate scintillation light, and the scintillation light is coupled to an optical fiber through the optical fiber coupling cone; afterwards, the scintillation light is transmitted to a far end through the optical fiber and is coupled to the gated photomultiplier; under the control of a gate signal, the gate-controlledphotomultiplier can avoid a high-intensity electromagnetic pulse at a zero moment and convert an optical signal into an electric pulse signal; and the digitizer converts the electric pulse signal intodigits and inputs the digits into the computer for recording and storage. The detector can be used for measuring various high-flux ions in occasions where strong electromagnetic pulse possibly blindsa traditional detector system and in various complex electromagnetic environments, and has the characteristics of strong anti-electromagnetic interference performance, large proton receiving flux andthe like.

Description

technical field [0001] The invention belongs to the technical field of radiation detection in physical experiments, and in particular relates to an anti-electromagnetic interference proton energy spectrum and intensity detector. Background technique [0002] In nuclear reactors and space satellite systems, it is often necessary to detect the strength and energy of protons, and these scenarios are often accompanied by various strong electromagnetic radiation. In these extreme environments, the electric field and magnetic field may be unusually high, making semiconductor detectors, micro-channel plate detectors, and CCD detectors unable to work normally due to electromagnetic interference. This effect is known as the blinding effect of intense radiation. This blinding effect may cause the detector to seriously deviate from linear response for a long period of time, fail to respond, or even destroy the detector. Usually the neutron spectrum of the reaction is measured by a re...
