bubble chamber

n.
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.

bubble chamber

n
(General Physics) a device that enables the tracks of ionizing particles to be photographed as a row of bubbles in a superheated liquid. Immediately before the particles enter the chamber the pressure is reduced so that the ionized particles act as centres for small vapour bubbles

cloud′ cham`ber


n.
an apparatus containing a mixture of gas and vapor in which visible tracks of ions reveal the paths of charged particles through the mixture.
[1895–1900]

bub·ble chamber

(bŭb′əl)
A device used to observe the movements of charged atomic particles, such as ions. A bubble chamber consists of a container filled with a very hot fluid. The paths of the charged particles are visible as trails of bubbles in the fluid. Bubble chambers are considered more useful than cloud chambers, because the bubbles remain visible longer than the condensation clouds of cloud chambers do. Compare cloud chamber.
