Bubble chamber
An instrument which can record the passage of high energy particles because of the ionisation they cause to the atoms or molecules of, for example, liquid hydrogen or helium, contained in the bubble chamber. As the high energy particles ionise the atoms they strike, energy is released which causes local boiling of the superheated liquid. This produces bubbles which show the path that the particle has taken. The tracks of bubbles are photographed and analysed. Their characteristics can reveal which particles created them, often together with their mass, momentum and charge.
