Nuclear radiation detection device capable of transmitting original signal in long distance

Abstract

The invention relates to a nuclear radiation detection device capable of transmitting an original signal in a long distance. The device comprises a detector located in a measurement area and a signal amplifier located at a remote position. The detector is connected with the signal amplifier through a coaxial cable, and a high voltage resistant connector is arranged between the detector and the coaxial cable; the anode of the detector is communicated with the wire core of the coaxial cable through the signal conduit of the high-voltage-resistant connector, so that signal transmission is realized. According to the device, only the detector of the device is located in a measurement area and can bear strong radiation and high temperature, and the signal amplifier is located at a position under a remote appropriate environmental condition, so that the device can work reliably for a long time.

Description

technical field [0001] The invention belongs to nuclear radiation measurement technology, in particular to a nuclear radiation detection device capable of long-distance transmission of original signals. Background technique [0002] The original signal generated by the nuclear radiation detector is very weak, so it needs to be connected to a signal amplifier to amplify the original signal and then transmitted to the main amplifier or signal acquisition equipment for signal processing. Usually the detector is directly connected to the signal amplifier, and the length of the wire is only a few centimeters. In some application scenarios, where the detector is located with strong nuclear radiation or high temperature, the detector will not be damaged at this time, and the amplifier cannot withstand environmental damage due to a large number of electronic components. Moreover, due to installation space or weight limitations, it is impossible to install shielding or cooling equipm...

[0002] The original signal generated by the nuclear radiation detector is very weak, so it needs to be connected to a signal amplifier to amplify the original signal and then transmitted to the main amplifier or signal acquisition equipment for signal processing. Usually the detector is directly connected to the signal amplifier, and the length of the wire is only a few centimeters. In some application scenarios, where the detector is located with strong nuclear radiation or high temperature, the detector will not be damaged at this time, and the amplifier cannot withstand environmental damage due to a large number of electronic components. Moreover, due to the limitation of installation space or weight, it is impossible to install shielding or cooling equipment outside the detector, so traditional nuclear radiation detectors cannot work stably for a long time under strong radiation or high temperature without engineering measures
