The ARGUS experiment was a particle physics experiment that ran at the electron-positron collider ring DORIS II at DESY. It is the first experiment that observed the mixing of the B mesons (in 1987).[1]

The ARGUS detector was a hermetic detector with 90% coverage of the full solid angle. It had drift chambers, a time-of-flight system, an electromagnetic calorimeter and a muon chamber system.[2]
