Radiation Observation Instruments Based on the Peltier Effect

Abstract

Ionising radiation consists of three types of radiation, alpha beta gamma, which are invisible to the naked eye. In order to observe ionising radiation with the naked eye, the Wilson cloud chamber was invented. The operation of Wilson cloud chamber requires the use of a disposable cold source such as dry ice, which has the disadvantage of short operating time and releasing a large amount of greenhouse gases. The semiconductor cooling chip is a solid-state thermoelectric device using the Peltier effect, which does not release any greenhouse gases during the working process. This paper explores the design and fabrication of an all-solid-state-cooled Wilson cloud chamber based on the working principle of semiconductor refrigeration discs, and fabricates an engineering prototype by means of 3D printing-based technology.
