Quadrapole magnets sometimes called correctors, are designed to create a magnetic field whose magnitude grows linearly with the radial distance from its longitudinal axis, which is usually centered on and parallel to the main motion of the charged particles. The net result of these fields is a focusing force in one plane and a defocusing one in the plane perpendicular to it. Current flowing through a wire produces a magnetic field (M) around the wire. ... In physics, a charged particle is a particle with an electric charge. ...
In a quadrapole electromagnet there are four steel pole tips, two opposing magnetic north poles and two opposing magnetic south poles. The steel is magnetized by a large electric current that flows in the coils of tubing wrapped around the poles. The old steel cable of a colliery winding tower Steel is a metal alloy whose major component is iron, with carbon being the primary alloying material. ... This is about the geographic meaning of North Pole. ... In electricity, current is the rate of flow of charges, usually through a metal wire or some other electrical conductor. ...
In a particle accelerator, the various magnets required to bend, steer and correct the particle beam make up 'the lattice'. The quadrupoles in the lattice are of two types: 'F quadrupoles' (which are horizontally focusing but vertically defocusing) and 'D quadrupoles' (which are vertically focusing but horizontally defocusing). This situation is due to the laws of electormagnetism (as described by the 'Maxwell Equations' which show that it is imposible for a quadrupole to focus in both planes at the same time.
If an F quadrupole and a D quadrupole are placed immediatly next to each other, they completely cancel out. But if there is a space between them (and the lenght of this has been correctly chosen0, the overall effect is focusing in both horizontal and vertical planes.
In particle accelerators, quadrupolemagnets are used to focus beams of charged particles.
They are designed to create magnetic fields whose magnitude grows linearly with the radial distance from its longitudinal axis, which is usually centered around and parallel to the main motion of the charged particles.
Several quadrupolemagnets can be arranged in sequence such that they create a net focusing effect in both planes.
