bubble chamber

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

(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

an apparatus containing a mixture of gas and vapor in which visible tracks of ions reveal the paths of charged particles through the mixture.

bub·ble chamber

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.

Physicists and astronomers, though, deal with WIMPs and MACHOs, giants and dwarfs, and bubble chambers.
Such an arrangement, which ended reliance on photographed particle tracks in bubble chambers and inaugurated the age of electronic particle detection, allowed physicists to pinpoint individual particle trajectories with improved precision while handling hundreds of thousands of such events per second.
His work includes experiments in the 25-inch and 40-inch bubble chambers at LBL and SLAC, work on the electron ring accelerator at LBL, pion and kaon form factor experiments at Fermilab, the Time Projection Chamber (TPC) at Berkeley/SLAC, the D0 experiment at Fermilab, the CMS experiment at CERN, the DREAM calorimeter tests at CERN, and numerous smaller physics and instrumentation studies.
