Meer, Simon van der

Meer, Simon van der

▪ Dutch physicist
born Nov. 24, 1925, The Hague, Neth.

      Dutch physical engineer who in 1984, with Carlo Rubbia (Rubbia, Carlo), received the Nobel Prize for Physics for his contribution to the discovery of the massive, short-lived subatomic particles designated W and Z that were crucial to the unified electroweak theory posited in the 1970s by Steven Weinberg, Abdus Salam, and Sheldon Glashow.

      After receiving a degree in physical engineering from the Higher Technical School in Delft, Neth., in 1952, van der Meer worked for the Philips Company. In 1956 he joined the staff of CERN (the European Organization for Nuclear Research), near Geneva, where he remained until his retirement in 1990.

      The electroweak theory provided the first reliable estimates of the masses of the W (W particle) and Z particles (Z particle)—nearly 100 times the mass of the proton. The most promising means of bringing about a physical interaction that would release enough energy to form the particles was to cause a beam of highly accelerated protons, moving through an evacuated tube, to collide with an oppositely directed beam of antiprotons. CERN's circular particle accelerator, four miles in circumference, was the first to be converted into a colliding-beam apparatus in which the desired experiments could be performed. Manipulation of the beams required a highly effective method for keeping the particles from scattering out of the proper path and hitting the walls of the tube. Van der Meer, in response to this problem, devised a mechanism that would monitor the particle scattering at a particular point on the ring and would trigger a device on the opposite side of the ring to modify the electric fields in such a way as to keep the particles on course.
