Virtuality and reality combined gamma spectrometer measuring system

Abstract

The invention discloses a virtuality and reality combined gamma spectrometer measuring system, and belongs to the technical field of nuclear engineering research. The system comprises a computer terminal, a router switch cluster, a digital multichannel analyzer, a radioactive source simulator and a photomultiplier, wherein the photomultiplier is matched with a detector for detecting gamma rays; signal transmission is carried out between the digital multichannel analyzer and the radioactive source simulator through a BNC connecting line; and the router switch cluster, the digital multichannel analyzer and the radioactive source simulator are all interconnected through a cable network. The radioactive source simulator respectively carries out signal transmission with the digital multichannelanalyzer and the photomultiplier, the photomultiplier is used for acquiring a real radioactive source signal through the detector, the radioactive source simulator provides a virtual radioactive source signal for the digital multichannel analyzer, and the virtuality and reality combined system can meet the requirements for nuclear physics teaching experiments, so that the teaching is more convenient and safer.

Description

technical field [0001] The invention relates to the technical field of nuclear engineering research, in particular to a gamma spectrometer measurement system combining virtual and real. Background technique [0002] Nuclear physics was born in the early 20th century. Its most common and well-known applications are: nuclear power generation and nuclear weapon technology, and the harm that nuclear weapons and nuclear pollution bring to human beings and nature often makes people "talk about nuclear discoloration". However, the benefits that nuclear physics brings to mankind can only be compared with modern electronics and information technology. [0003] The reason why nuclear physics research is valued by people and strongly supported by society is closely related to its extensive and important application value. There is almost no nuclear physics laboratory that is not engaged in applied research of nuclear technology. Some facilities even work primarily on nuclear technolo...
