This light guide comes from the large CERN particle physics laboratory outside Geneva, where the smallest particles of matter are studied. The experiments often involve hundreds of researchers, and the equipment is both large and small. Light guides like this one were used in an experiment to find “W” and “Z” particles. The energy from incoming particles is reradiated as light using the light guides, but with a lower energy. Light guides were used to adjust the radiation so that it matches the sensitivity of the apparatus and gives better measurements. The experiment earned Carlo Rubbia and Simon van der Meer the Nobel Prize in Physics in 1984.
The light guide was donated to the Nobel Prize Museum by CERN in 2000. - Person
