Radiation intensity detector based on multi-index SiGe HBT

Abstract

A radiation intensity detector based on multi-index SiGe HBT comprises the following units connected in series in order: a 38 decoder, a first socket providing a connection effect, a detachable radiation intensity detection array, a second socket providing a connection effect, a filter array and an A / D conversion circuit array and a FPGA chip; the FPGA chip signal input end is connected with a matrix keyboard; the FPGA chip output end is connected with a LCD and the 38 decoder input end; the detachable radiation intensity detection array comprises a plurality of detection units with the same structure; each detection unit input end is connected with the 38 decoder output end through the first socket; each detection unit output end is connected with the filter array input end through the second socket. The radiation intensity detector can fast and efficiently detect the proton radiation, ionising radiation and neutron radiation intensities, can be applied to the radiation sensitive workareas in the aviation spaceflight field and a nuclear power station, and can be applied to the daily production life.

Description

technical field [0001] The invention relates to a radiation intensity detector. In particular, it relates to a radiation intensity detector based on a multi-finger SiGe HBT for detecting the radiation intensity of a radiation source in space. Background technique [0002] With the development of aerospace technology and nuclear power technology, radiation problems have gradually attracted people's attention. In daily life and scientific research work, we usually want to measure the radiation intensity of proton radiation, ionizing radiation and neutron radiation, so as to carry out radiation early warning and qualitative analysis of radiation. At the same time, we also hope that the detector used can quickly and efficiently detect changes in radiation intensity. In addition, we also hope that the radiation detection device used is relatively low in price and can be used in a wide range of applications. However, the detection of radiation by existing radiation detectors is...

Problems solved by technology

However, the detection of radiation by existing radiation detectors is limited to a single radiation, and the ionizing radiation detection device needs an additional DSP module to convert the frequency of the signal due to the influence of the antenna bandwidth, which greatly increases the production cost of the radiation detector and is not conducive to radiation intensity detection.
