Fission chain reaction dynamic demonstrator

Abstract

The invention discloses a dynamic demonstration instrument for nuclear fission chain reaction, which comprises a bracket, a glass container, a baseplate, a ball inlet, a rocking cylinder, an air pump, a blowing mouth, a programmable controller, a fission neutron ball and an incident neutron ball. The glass container is arranged on the bracket; the baseplate is arranged under the glass container; a together-aligned atomic nucleus model is arranged on the baseplate; a recession is positioned on the baseplate, which is corresponding to the atomic nucleus model; the fission neutron ball is arranged inside the recession; the blowing mouth is arranged at the lower part at the lateral side of the glass container; the shaft of the rocking cylinder bears one side of the baseplate at the bottom of the baseplate; the ball inlet is situated upon the glass container; and the rocking cylinder is connected with the programmable controller. The demonstration instrument of the invention dynamically demonstrates the nuclear fission chain reaction, thus facilitating the popularization of science and education for the knowledge about nuclear fission.

Description

technical field [0001] The invention relates to a dynamic demonstration instrument for demonstrating nuclear fission chain reaction. Background technique [0002] Nuclear fission is the process of splitting an atomic nucleus into several atomic nuclei. Only some atomic nuclei with very large masses, such as uranium and thorium, can undergo nuclear fission. Under the bombardment of a neutron, the nuclei of these atoms will split into two or more nuclei with smaller masses, releasing two to three neutrons and a lot of energy at the same time, and the newly produced neutrons can make other nuclei Nuclear fission ensues..., thereby continuing the fission process, which is called a chain reaction. The nuclear fission chain reaction process occurs instantaneously. At present, there is a lack of science popularization exhibits related to nuclear fission in China, especially there is no dynamic demonstration instrument for nuclear fission chain reaction, which is not conducive to...
