Antenna (radio)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic wave In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visib ...s (radio waves). In Receiver (radio), reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be Amplifier, amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor (material), conductors (Driven element, elements), elect ...

John Cockcroft
Sir John Douglas Cockcroft, (27 May 1897 – 18 September 1967) was a British physicist who shared with Ernest Walton the Nobel Prize in Physics in 1951 for splitting the atomic nucleus, and was instrumental in the development of nuclear power. After service on the Western Front with the Royal Field Artillery during the Great War, Cockcroft studied electrical engineering at Manchester Municipal College of Technology whilst he was an apprentice at Metropolitan Vickers Trafford Park and was also a member of their research staff. He then won a scholarship to St. John's College, Cambridge, where he sat the tripos exam in June 1924, becoming a wrangler. Ernest Rutherford accepted Cockcroft as a research student at the Cavendish Laboratory, and Cockcroft completed his doctorate under Rutherford's supervision in 1928. With Ernest Walton and Mark Oliphant he built what became known as a Cockcroft–Walton generator. Cockcroft and Walton used this to perform the first artifi ...

List Of Streets At CERN
The European Organization for Nuclear Research (CERN) is an international, intergovernmental organisation. Its activities are carried out on land placed at its disposal by the Canton of Geneva, the Swiss Confederation and France. In accordance with the agreements reached between France, Switzerland and CERN governing the organisation's legal status, the CERN site is placed under the authority and control of the Director-General as the organisation's chief executive officer. The latter is thus empowered to issue internal rules applicable to all persons entering the CERN site and intended to establish thereon the conditions necessary for the exercise of its functions. CERN street names were for a long time an internal matter to the organisation. In 2013 the Canton of Geneva officially recognised CERN street names.

Meyrin
Meyrin () is a municipality of the Canton of Geneva, Switzerland. The main site of CERN, the European particle physics research organisation, is in Meyrin. Meyrin was originally a small agricultural village until the 1950s, when construction of CERN began just to the north. It is now a commuter town dominated with apartment high-rises, and many of its residents work at CERN or in central Geneva. Geneva International Airport is partially located within Meyrin.Plan de commune ." Meyrin. Retrieved on 29 September 2009.

John Adams (physicist)
Sir John Bertram Adams (24 May 1920 – 3 March 1984) was an English accelerator physicist and administrator. Adams is mostly known for his work at CERN and Culham Laboratory. Despite a lack of formal university education, Adams worked for organizations like the Telecommunications Research Establishment and the Atomic Energy Research Establishment in the 1940s and early 1950s. He served as acting director and eventually as elected director of CERN, from 1976 until 1981. Biography Early life Born in Kingston, Surrey on May 24, 1920. He attend Eltham College from 1931 until 1936, after which he began to work for Siemens Laboratories in Woolwich. He continued studying at the South East London Technical Institute until 1939 earning a Higher National Certificate. This was the end of his formal education receiving no university education. Professional career at Siemens, his work was concerned with the acoustic properties of telephones. Between 1940 and 1945, he worked th ...

Strong Focusing
In accelerator physics strong focusing or alternating-gradient focusing is the principle that, using sets of multiple electromagnets, it is possible to make a particle beam simultaneously converge in both directions perpendicular to the direction of travel. By contrast, weak focusing is the principle that nearby circles, described by charged particles moving in a uniform magnetic field, only intersect once per revolution. Earnshaw's theorem shows that simultaneous focusing in two directions transverse to the beam axis at once by a single magnet is impossible - a magnet which focuses in one direction will defocus in the perpendicular direction. However, iron "poles" of a cyclotron or two or more spaced quadrupole magnets (arranged in quadrature) can alternately focus horizontally and vertically, and the net overall effect of a combination of these can be adjusted to focus the beam in both directions. Strong focusing was first conceived by Nicholas Christofilos in 1949 but not pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolf Widerøe
Rolf Widerøe (11 July 1902 – 11 October 1996) was a Norwegian accelerator physicist who was the originator of many particle acceleration concepts, including the ''resonance accelerator'' and the betatron accelerator. Early life Widerøe was born in Kristiania (now Oslo) in 1902 as a son of the mercantile agent Theodor Widerøe (1868–1947) and Carla Johanne Launer (1875–1971). He was a brother of the aviator and entrepreneur Viggo Widerøe who became the founder of the Norwegian airline Widerøe. After his A-level exams (Examen artium) in the summer of 1920 at the Halling School in Oslo, Widerøe left for Karlsruhe, Germany, to study electrical engineering. Betatron accelerator concept There he conceived the concept of electromagnetic induction to accelerate electrons, which became the basis of what would be known as betatron. This idea was to use a vortex field surrounding a magnetic field to accelerate electrons in a tube. Return to Germany In 1924, he returned to Norw ...
