Injection kicker magnets
Encyclopedia
Injection kicker magnets are dipole magnet
s used to "kick" an incoming particle beam
into a circular accelerator called a synchrotron
. The magnets are powered by a high voltage (usually in the range of tens of thousands of volt
s) source called a power modulator that produce a short pulse of current (usually in the range of a few billionths of a second
to about one millionth of a second long and thousands of ampere
s in amplitude). The current produces a magnetic field
in the magnet, that in turn imparts a Lorentz force
on the particles as they traverse the magnet's length, causing the beam to deflect into the proper trajectory to be stored in the synchrotron ring.
Dipole magnet
A dipole magnet, in particle accelerators, is a magnet constructed to create a homogeneous magnetic field over some distance. Particle motion in that field will be circular in a plane perpendicular to the field and collinear to the direction of particle motion and free in the direction orthogonal...

Particle beam
A particle beam is a stream of charged or neutral particles which may be directed by magnets and focused by electrostatic lenses, although they may also be self-focusing ....

Synchrotron
A synchrotron is a particular type of cyclic particle accelerator in which the magnetic field and the electric field are carefully synchronised with the travelling particle beam. The proton synchrotron was originally conceived by Sir Marcus Oliphant...

Volt
The volt is the SI derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honor of the Italian physicist Alessandro Volta , who invented the voltaic pile, possibly the first chemical battery.- Definition :A single volt is defined as the...

Second
The second is a unit of measurement of time, and is the International System of Units base unit of time. It may be measured using a clock....

Ampere
The ampere , often shortened to amp, is the SI unit of electric current and is one of the seven SI base units. It is named after André-Marie Ampère , French mathematician and physicist, considered the father of electrodynamics...

Magnetic field
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude ; as such it is a vector field.Technically, a magnetic field is a pseudo vector;...

Lorentz force
In physics, the Lorentz force is the force on a point charge due to electromagnetic fields. It is given by the following equation in terms of the electric and magnetic fields:...
