Description
The diffusion cloud chamber is a classical yet powerful tool for visualizing the trajectories of ionizing radiation. Its use in education provides students with a direct and intuitive understanding of radioactive decay, particle interactions, and the principles of radiation detection. This poster presents practical aspects of constructing, operating, and maintaining a diffusion-type cloud chamber for didactic purposes. Practical experience with optimizing visibility of particle tracks through control of temperature gradient, supersaturation conditions, and illumination is described. Different cooling methods, alcohol types, chamber geometries, and background radiation sources are compared in terms of performance and safety. Experience from laboratory demonstrations and classroom activities is discussed, highlighting the cloud chamber’s pedagogical value in teaching concepts of nuclear physics and radiation protection. The presented poster demonstrates that even a relatively simple and low-cost setup can effectively support experiential learning in both secondary and university-level education.
