Simon Van der Meer (born 1925), Dutch physicist at CERN, the European particle physics laboratory outside Geneva. In the early 1970s, Van der Meer invented a technique for storing & concentrating antiprotons so that they would form a dense beam. This method, called stochastic cooling, is used in CERN's Antiproton Accumulator, from which antiprotons are injected into the Super-Proton- Synchrotron (SPS) accelerator & collided with protons. Use of the SPS as a proton-antiproton collider led to the 1983 discovery of the W & Z particles, the carriers of the weak force, for which Van der Meer shared the 1984 Nobel Prize for physics with Carlo Rubbia.
