Embodiment 1

[0045] NaI(Tl) scintillation spectrometer experiment (an energy spectrum measurement experiment) using the nuclear physics experiment simulation system

[0046] Experimental principle:

[0047] The particles emitted by the nuclear radioactive source interact with NaI(Tl) crystals to generate fluorescence, which is amplified by the photomultiplier tube and converted into a voltage pulse. The energy spectrum of the corresponding radioactive source is obtained by measuring and statistically analyzing the output voltage pulse of the photomultiplier tube. . This experiment allows students to learn the structure and principle of the energy spectrometer, and learn to use the energy spectrum to perform energy spectrum measurement.

[0058] Experimental principle:

[0059] When the γ-ray passes through the material, it interacts with the material, and the photon is absorbed, so that the output ray intensity is as low as the input ray intensity, and the attenuation of the ray intensity with the thickness of the material obeys the exponential law. This experiment mainly verifies the absorption law of narrow-beam gamma rays in matter.

technical field [0001] The invention relates to a nuclear physics experiment simulation experiment equipment and a simulation method, in particular to a nuclear physics experiment simulation system and a method for performing an energy spectrum measurement experiment and an intensity measurement experiment. Background technique [0002] The real nuclear physics experiment platform consists of nuclear radioactive sources, nuclear radiation detectors and nuclear electronics processing systems. Because the nuclear radiation produced by radioactive sources is likely to cause environmental pollution and personal injury, many universities and research institutes are now trying to use simulation technology to complete nuclear physics experiments. The current simulation methods include two: one is pure software simulation, that is, on the computer The nuclear physics experiment process is simulated through the corresponding software, and the second is to use the nuclear signal gener...
