View of the 110-metre long vacuum chamber of the neutral kaon detector at CERN, the European particle physics laboratory near Geneva. Commissioned in the mid-1980s, the detector is designed to compare the decays of long-lived & short-lived neutral kaons into electrically charged or neutral pairs of pions. The experiment hopes to amass data to clarify the mystery of CP (charge/parity) violation, the slight asymmetry in nature that produces a preponderance of matter over antimatter.
