List of Super Proton Synchrotron experiments

From Wikipedia, the free encyclopedia

This is a list of past and current experiments at the CERN Super Proton Synchrotron (SPS) facility since its commissioning in 1976.[1] The SPS was used as the main particle collider for many experiments, and has been adapted to various purpose ever since its inception. Four locations were used for experiments, the North Area (NA experiments), West Area (WA experiments), Underground Area (UA experiments), and the Endcap MUon detectors (EMU experiments).

The UA1 and UA2 experiments famously detected the W and Z bosons in the early 1980s.[2] Following this, Carlo Rubbia and Simon van der Meer won the 1984 Nobel Prize in Physics.[3]

The list is first compiled from the INSPIRE-HEP database, then missing information is retrieved from the online version CERN's Grey Book. The most specific information of the two is kept, e.g. if the INSPIRE database lists November 1974, while the Grey Book lists 22 November 1974, the Grey Book entry is shown. When there is a conflict between the INSPIRE database and the Grey Book, the INSPIRE database information is listed, unless otherwise noted.
