Inventor: Charles Thomson Rees Wilson.
What it is made of
- Glass cloud chamber — has part. A volume filled with saturated vapour.
- Piston — has part. A sudden expansion supersaturates the vapour.
- Glass window — has part. Observing and photographing the tracks.
Principles and materials it uses
- Latent heat — uses. Supersaturated vapour.
- Radioactivity — uses. Particle tracks.
- Glass — is made of. The chamber is a glass vessel.
- Ethanol — is made of. It is saturated with alcohol or water vapour.
History: what it evolved from and what it influenced
- Bubble chamber — evolved into. A liquid instead of vapour.
