2 m Bubble Chamber (CERN)

A "2 m Bubble Chamber" refers to a specific type of bubble chamber that has a diameter of approximately 2 meters, used in particle physics experiments, including those conducted at CERN (the European Organization for Nuclear Research). ### What is a Bubble Chamber? A bubble chamber is a sealed container filled with a superheated liquid, usually hydrogen or another suitable fluid. When charged particles pass through the chamber, they ionize the liquid along their paths, creating nucleation points where bubbles can form.
