Vinod Chohan
Vinod Chandrasinh Chohan (1 May 1949 – 12 June 2017) was a Tanzanian-born accelerator specialist and engineer. He was a Senior Staff Member at CERN for nearly 40 years. He held a leading position at CERN's Antiproton Accumulator, a machine that was part of the infrastructure connected to the UA1 and UA2 experiments, where the W and Z bosons were discovered in 1983. Carlo Rubbia and Simon van der Meer received the 1984 Nobel Prize in Physics for this discovery. Chohan worked closely with the latter on the antiproton accumulator. Chohan was a substantial contributor to the Large Hadron Collider (LHC), leading the team that tested, measured and trained more than a thousand superconducting magnets for the LHC. During his nearly 40 years as a staff member at CERN he held technical and management positions such as in beam diagnostics, instrumentation, accelerator studies, controls, testing of superconducting magnet and safety.

Dar Es Salaam
Dar es Salaam (, ; from ) is the largest city and financial hub of Tanzania. It is also the capital of the Dar es Salaam Region. With a population of over 7 million people, Dar es Salaam is the largest city in East Africa by population and the List of cities in Africa by population, fifth-largest in Africa. Located on the Swahili coast, Dar es Salaam is an important economic center and one of the fastest-growing cities in the world.

Horizon (UK TV Series)
''Horizon'' is an ongoing and long-running British documentary television series on BBC Two that covers science and philosophy. History The programme was first broadcast on 2 May 1964 with "The World of Buckminster Fuller", which explored the theories and structures of inventor Richard Buckminster Fuller and included the ''Horizon'' mission statement: "The aim of ''Horizon'' is to provide a platform from which some of the world's greatest scientists and philosophers can communicate their curiosity, observations and reflections, and infuse into our common knowledge their changing views of the universe". ''Horizon'' continues to be broadcast on BBC Two, and in 2009 added a series of films based on the rich ''Horizon'' archive, called ''Horizon Guides'', on BBC Four. In December 2016, it was announced that ''Horizon'' would no longer be made exclusively by the BBC's in-house production division, BBC Studios, and the BBC invited independent production companies to pitch to make episo ...

Big Bang
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models based on the Big Bang concept explain a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure. The uniformity of the universe, known as the horizon and flatness problems, is explained through cosmic inflation: a phase of accelerated expansion during the earliest stages. A wide range of empirical evidence strongly favors the Big Bang event, which is now essentially universally accepted.: "At the same time that observations tipped the balance definitely in favor of the relativistic big-bang theory, ..." Detailed measurements of the expansion rate of the universe place the Big Bang singularity at an estimated billion years ago, which is considered the age of the universe. Extrapolating this cosmic expansion backward in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Super Proton Synchrotron
The Super Proton Synchrotron (SPS) is a particle accelerator of the synchrotron type at CERN. It is housed in a circular tunnel, in circumference, straddling the border of France and Switzerland near Geneva, Switzerland. History The SPS was designed by a team led by John Adams (physicist), John Adams, List of Directors General of CERN, director-general of what was then known as Laboratory II. Originally specified as a 300 GeV accelerator, the SPS was actually built to be capable of 400 GeV, an operating energy it achieved on the official commissioning date of 17 June 1976. However, by that time, this energy had been exceeded by Fermilab, which reached an energy of 500 GeV on 14 May of that year. The SPS has been used to accelerate protons and antiprotons, electrons and positrons (for use as the injector for the Large Electron–Positron Collider (LEP)), and quark–gluon plasma, heavy ions. From 1981 to 1991, the SPS operated as a hadron (more precisely, proton–an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiproton
The antiproton, , (pronounced ''p-bar'') is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy. The existence of the antiproton with electric charge of , opposite to the electric charge of of the proton, was predicted by Paul Dirac in his 1933 Nobel Prize lecture. Dirac received the Nobel Prize for his 1928 publication of his Dirac equation that predicted the existence of positive and negative solutions to Einstein's energy equation (E = mc^2) and the existence of the positron, the antimatter analog of the electron, with opposite charge and spin. The antiproton was first experimentally confirmed in 1955 at the Bevatron particle accelerator by University of California, Berkeley physicists Emilio Segrè and Owen Chamberlain, for which they were awarded the 1959 Nobel Prize in Physics. In terms of valence quarks, an antiproton consists o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proton Synchrotron
The Proton Synchrotron (PS, sometimes also referred to as CPS) is a particle accelerator at CERN. It is CERN's first synchrotron, beginning its operation in 1959. For a brief period the PS was the world's highest energy particle accelerator. It has since served as a pre-accelerator for the Intersecting Storage Rings (ISR) and the Super Proton Synchrotron (SPS), and is currently part of the Large Hadron Collider (LHC) accelerator complex. In addition to protons, PS has accelerated alpha particles, oxygen and sulfur nuclei, electrons, positrons, and antiprotons. Today, the PS is part of CERN's accelerator complex. It accelerates protons for the LHC as well as a number of other experimental facilities at CERN. Using a negative hydrogen ion source, the ions are first accelerated to the energy of 160 MeV in the linear accelerator CERN Hadron Linacs#LINAC 4, Linac 4. The hydrogen ion is then stripped of both electrons, leaving only the nucleus containing one proton, which is injected i ...
