A cloud chamber, also known as the Wilson chamber, is a particle detector used for detecting ionizing radiation. They are sealed environment containing a supersaturated vapor of water or alcohol. When a charged particle interacts with the mixture, it ionizes it. The resulting ions act as condensation nuclei, around which a mist will form.
