The Wilson cloud chamber is a device used in particle physics to detect charged particles. There are a few synonyms for the Wilson cloud chamber that are commonly used in the field. One such synonym is the cloud chamber, as it is commonly referred to just by this name. Another synonym that is sometimes used is a diffusion cloud chamber, as it uses a diffusion process to create a visible cloud of vapor from charged particles passing through. Additionally, some researchers may refer to it as a Wilson chamber or an expansion chamber. Regardless of the name used, the Wilson cloud chamber remains a valuable tool for studying particle physics.
