A bubble chamber is a pool filled with a liquid (typically hydrogen) such that its molecules are ionized to the passage of a charged particle, thus producing bubbles. In this way the trajectories of the particles are visible and it is possible to study the various decays(2).
The bubble chamber was invented by Donald Glaser(1) in 1952, who win the Nobel Prize in 1960.
