Simon van der Meer (24 November 1925 – 4 March 2011) was a Dutch particle accelerator physicist who shared the Nobel Prize in Physics in 1984 with Carlo Rubbia for contributions to the CERN project which led to the discovery of the W and Z particles, the two fundamental communicators of the weak interaction.
The technique was invented and applied at the Intersecting Storage Rings, [2] and later the Super Proton Synchrotron (SPS), at CERN in Geneva, Switzerland, by Simon van der Meer, [3] a physicist from the Netherlands.
Simon van der Meer in the Antiproton Accumulator Control Room, 1984. The creation and storage of antiprotons in sufficient numbers were one of the biggest challenges in the construction of the Sp p S. The production of antiprotons required use of existing CERN infrastructure, such as the Proton Synchrotron (PS) and the Antiproton Accumulator ...
UA2, together with the UA1 experiment, succeeded in discovering these particles in 1983, leading to the 1984 Nobel Prize in Physics being awarded to Carlo Rubbia and Simon van der Meer. The UA2 experiment also observed the first evidence for jet production in hadron collisions in 1981, and was involved in the searches of the top quark and of ...
These particles have a mass almost 100 times greater than the proton. In 1984 Carlo Rubbia and Simon van der Meer were awarded the Nobel Prize "for their decisive contributions to the large project, which led to the discovery of the field particles W and Z, communicators of weak interaction".

A magnetic horn or neutrino horn (also known as the Van der Meer horn) is a high-current, pulsed focusing device, invented by the Dutch physicist Simon van der Meer in CERN, that selects pions and focuses them into a sharp beam. The original application of the magnetic horn was in the context of neutrino physics, where beams of pions have to be ...
Carlo Rubbia and Simon van der Meer received the Prize in 1984. After Gerardus 't Hooft showed the Glashow–Weinberg–Salam electroweak interactions to be mathematically consistent, the electroweak theory became a template for further attempts at unifying forces.
bosons were seen in January 1983 during a series of experiments made possible by Carlo Rubbia and Simon van der Meer. The actual experiments were called UA1 (led by Rubbia) and UA2 (led by Pierre Darriulat), [9] and were the collaborative effort of many people. Van der Meer was the driving force on the accelerator end (stochastic cooling). UA1 ...
