Description

Technical Field

[0001] The utility model relates to the technical field of experiments, in particular to a low-energy nuclear reaction experimental device. Background Art

[0002] At present, in order to verify the existence of low-energy nuclear reactions, some people have proposed that low-energy nuclear reactions are nuclear fission reactions. Nuclear fission will definitely be accompanied by the production of neutrons and charged particle fragments. By detecting neutrons and charged particles, it can be proved that a low-energy nuclear reaction has occurred.

[0003] When conducting experiments to detect neutrons and charged particles, a laser is required to irradiate a container containing titanium sheets in a hydrogen environment. After a long period of irradiation, the two detectors in the container are removed and then etched to count the number of neutrons and charged particles.

[0004] However, there are only two detectors in the container, which results in low detection accuracy. Utility Model Content
