Cloud-chamber Synonyms

A device used to observe the movements of charged atomic and subatomic particles, such as ions, electrons, or muons. Cloud chambers consist of a closed container filled with a gas that is on the verge of condensing. Charged particles passing through the gas ionize the atoms in their path, forming visible lines of condensation.

Apparatus that detects the path of high-energy particles passing through a supersaturated vapor; each particle ionizes molecules along its path and small droplets condense on them to produce a visible track
