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.
