Surrounding type liquid scintillator intelligent energy disperse spectroscopy system and signal processing method thereof

Abstract

The invention provides a surrounding type liquid scintillator intelligent energy disperse spectroscopy system. The surrounding type liquid scintillator intelligent energy disperse spectroscopy systemcomprises a direct-current power management module, a gamma detector module, a signal regulation module, an ADC data sampling module, an FPGA micro-control system module and an LCD display module. A signal processing method of the surrounding type liquid scintillator energy disperse spectroscopy system comprises the following steps: acquiring working voltage adapted to different working modules ofthe surrounding type liquid scintillator energy disperse spectroscopy system; acquiring continuous pulse signals; filtering an amplified signal; carrying out ADC sampling on an analog signal obtainedafter filtering to obtain a digital signal; inputting the digital signal into an FPGA micro-control system circuit, then processing, by an FPGA micro-control system, the digital signal into data displayed by an LCD display circuit; inputting the processed signal into the LCD display circuit through a data transmission line and displaying the signal. According to the system, an operation interfaceis more optimized; the system is intelligent, is capable of effectively capturing gamma photons, and is high in energy counting rate.

Description

technical field [0001] The invention belongs to the field of data measurement, and relates to a data measurement instrument, in particular to a surround-type liquid scintillator intelligent energy spectrometer system and a signal processing method thereof. Background technique [0002] In recent years, with the rapid development of nuclear technology, nuclear technology has been widely used in many fields such as industry, geology, medicine, archaeology, etc.; nuclear technology is also playing an increasingly important role in these fields. But with the rapid development of nuclear technology, the potential threat it brings has attracted more and more attention. As a basic method of radiation measurement, gamma spectrum analysis is widely used in nuclear radiation detection, nuclide identification and other occasions. By measuring the gamma rays emitted when radioactive substances decay, the total amount of gamma radiation can be obtained, and information such as the eleme...

Problems solved by technology

[0003] The functions of most energy spectrometers on the market are too single, which is not in line with the trend of intelligent instruments in modern society; in addition, the scintillators of most energy spectrometers use crystal scintillators, and the shape of crystal scintillators is fixed. Unchanged, so the detection field of view is fixed and the detection surface
