A bubble chamber is a device for detecting charged subatomic particles. The sealed chamber is filled with a liquefied gas, such as liquid hydrogen, which is superheated. As particles move through the liquid, they leave trails of bubbles that can be illuminated and photographed. Such tracks can be used to identify particles, study their behavior, and analyze the complex events in which they participate. The inventor of the bubble chamber experimented with prototypes filled with what liquid?
Lucy Maud Montgomery
