An apparatus in which the movement and collision of ionizing particles is determined by the examination of trails of gas bubbles that form in the paths of the particles as they move through a superheated liquid.
A container filled with a superheated, transparent liquid in which charged atomic particles and their collisions can be studied by photographing the bubbles and violent boiling that occur along their paths.
A device used to observe the paths of charged subatomic particles. A bubble chamber consists of a container filled with very dense fluid that is close to boiling. The moving particles create tracks of bubbles in the fluid that can be photographed and analyzed. Bubble chambers have been largely supplanted in laboratories by more sensitive particle detectors that do not rely on the human eye.
