Big European Bubble Chamber

（重定向自BEBC）

The Big European Bubble Chamber (BEBC) is a piece of equipment formerly used to study particle physics at CERN. BEBC was installed at CERN in the early 1970s. It is a stainless-steel vessel which was filled with 35 cubic metres of liquid hydrogen, D₂ (molecular deuterium) or a hydrogen/neon mixture, whose sensitivity was regulated by means of a piston weighing 2 tonnes. During each expansion, charged particles left trails of bubbles as they passed through it. It has since been decommissioned and is now on display at CERN's Microcosm museum.
