UA5 Experiment
The UA5 experiment was the first experiment conducted at the Proton-Antiproton Collider (SpS), a collider using the infrastructure of the Super Proton Synchrotron (SPS). The experiment was approved in February 1979, as a collaboration between CERN and the universities of Bonn, Brussels, Cambridge and Stockholm. The spokesperson of the UA5 collaboration was John Rushbrooke. The object of the experiment was to investigate Centauro events and more generally to perform a first rapid visual survey of the energy region afforded by the then new SPS collider. Measurements were done on proton-antiproton collisions of 540 GeV center-of-mass energy, with the results being published in November 1983. Later, under the name of UA5/2, data was recorded from 900 GeV collisions. No indication of Centauro production was observed, but an upper limit on the production was obtained. The experimental setup consisted of two large streamer chambers which were placed above and below the SpS beam p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Gordon Rushbrooke
John Gordon Rushbrooke (1936–2003) was an Australian particle physicist. The son of Neil and Vera Rushbrooke, with four sisters, Rushbrooke was born in Geelong in 1936 and was brought up there. He attended Geelong Grammar School, where he was at the top of every class. Rushbrooke went on to Trinity College in Perth, graduating with a BSc in 1956. This was followed by a master's degree at Australia's first cyclotron, where he began his work as a high-energy physicist. His thesis from the University of Melbourne was on Coulomb excitations of the atom. In 1959 Rushbrooke won a scholarship that took him to King's College, Cambridge. Following work at the Cavendish Laboratory and completion of his PhD, Rushbrooke spent a year at CERN in Geneva before returning to Cambridge to take up a fellowship at Downing College as director of studies in physics. For five years from 1977 he was on leave from his duties at Cambridge, based again at CERN, where he became the spokesperson for the ...

INSPIRE-HEP
INSPIRE-HEP is an open access digital library for the field of high energy physics (HEP). It is the successor of the Stanford Physics Information Retrieval System (SPIRES) database, the main literature database for high energy physics since the 1970s. History SPIRES was (in addition to the CERN Document Server (CDS), arXiv and parts of Astrophysics Data System) one of the main Particle Information Resources. A survey conducted in 2007 found that SPIRES database users wanted the portal to provide more services than the, at that time, already 30-year-old system could provide. On the second annual Summit of Information Specialists in Particle Physics and Astrophysics in May 2008, the physics laboratories CERN, DESY, SLAC and Fermilab therefore announced that they would work together to create a new Scientific Information System for high energy physics called INSPIRE. It interacts with other HEP service providers like arXiv.org, Particle Data Group, NASA's Astrophysics Data System. and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UA2 Experiment
The Underground Area 2 (UA2) experiment was a high-energy physics experiment at the Proton-Antiproton Collider (SpS) — a modification of the Super Proton Synchrotron (SPS) — at CERN. The experiment ran from 1981 until 1990, and its main objective was to discover the W and Z bosons. 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 (particle physics), jet production in hadron collisions in 1981, and was involved in the searches of the top quark and of Superpartner, supersymmetric particles. Pierre Darriulat was the spokesperson of UA2 from 1981 to 1986, followed by Luigi Di Lella from 1986 to 1990. Background Around 1968 Sheldon Glashow, Steven Weinberg, and Abdus Salam came up with the electroweak theory, which unified electromagnetism and weak interactions, and for which they shared t ...

UA1 Experiment
The UA1 experiment (an abbreviation of Underground Area 1) was a high-energy physics experiment that ran at CERN's Proton-Antiproton Collider (SpS), a modification of the one-beam Super Proton Synchrotron (SPS). The data was recorded between 1981 and 1990. The joint discovery of the W and Z bosons by this experiment and the UA2 experiment in 1983 led to the Nobel Prize for physics being awarded to Carlo Rubbia and Simon van der Meer in 1984. Peter Kalmus and John Dowell, from the UK groups working on the project, were jointly awarded the 1988 Rutherford Medal and Prize from the Institute of Physics for their outstanding roles in the discovery of the W and Z particles. It was named as the first experiment in a CERN "Underground Area" (UA), i.e. located underground, outside of the two main CERN sites, at an interaction point on the SPS accelerator, which had been modified to operate as a collider. The UA1 central detector was crucial to understanding the complex topology of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Super Proton Synchrotron Experiments
This is a list of past and current experiments at the CERN Super Proton Synchrotron (SPS) facility since its commissioning in 1976. 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. Following this, Carlo Rubbia and Simon van der Meer Simon van der Meer (24 November 19254 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 part ... won the 1984 Nobel Prize in Physics.

Spark Chamber
{{short description, Charged particle detector A spark chamber is a particle detector: a device used in particle physics for detecting electrically charged particles. They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and silicon detectors. Today, working spark chambers are mostly found in science museums and educational organisations, where they are used to demonstrate aspects of particle physics and astrophysics. Spark chambers consist of a stack of metal plates placed in a sealed box filled with a gas such as helium, neon or a mixture of the two. When a charged particle from a cosmic ray travels through the box, it ionises the gas between the plates. Ordinarily this ionisation would remain invisible. However, if a high enough voltage can be applied between each adjacent pair of plates before that ionisation disappears, then sparks can be made to form along the trajectory taken by the ...

Centauro Event
A Centauro event is a kind of anomalous event observed in cosmic-ray detectors since 1972. They are so named because their shape resembles that of a centaur: i.e., highly asymmetric. If some versions of string theory are correct, then high-energy cosmic rays could create black holes when they collide with molecules in the Earth's atmosphere. These black holes would be tiny, with a mass of around 10 micrograms. They would also be unstable enough to explode in a burst of particles within around 10−27 seconds. Theodore Tomaras, a physicist at the University of Crete in Heraklion, Greece, and his Russian collaborators hypothesize that these miniature black holes could explain certain anomalous observations made by cosmic-ray detectors in the Bolivian Andes and on a mountain in Tajikistan. In 1972, the Andean detector registered a cascade that was strangely rich in charged, quark-based particles; far more particles were detected in the bottom portion of the detector tha ...
