Gargamelle

From Wikipedia, the free encyclopedia

Gargamelle was a giant particle detector at CERN, designed mostly for the detection of neutrinos. With a diameter of nearly 2 meter and 4.8 meter in length, Gargamelle was a bubble chamber that held nearly 12 cubic meters of freon (CF₃Br). It operated from 1970 to 1978 at the CERN Proton Synchrotron and Super Proton Synchrotron. Weak neutral currents were predicted in 1973 and confirmed shortly thereafter, in 1974, in Gargamelle.

The name derives from the giantess Gargamelle in the works of Rabelais; she was Gargantua's mother.
