B0214400 (bā′tə-trŏn′, bē′-)n. A magnetic induction electron accelerator capable of accelerating electrons to energies of several hundred million electron volts.

betatron

(ˈbiːtəˌtrɒn) n (Atomic Physics) a type of particle accelerator for producing high-energy beams of electrons, having an alternating magnetic field to keep the electrons in a circular orbit of fixed radius and accelerate them by magnetic induction. It produces energies of up to about 300 MeV

be•ta•tron

(ˈbeɪ təˌtrɒn; esp. Brit. ˈbi-)
n. an accelerator in which electrons are accelerated to high energies by an electric field. [1940–45; beta (see beta particle) + -tron]

Betatron

A device for accelerating charged particles in an orbit by means of the electric field E from a slowly changing magnetic flux &PHgr;. The electric field is given by E = -(1/2&pgr;r_o) d&PHgr;/dt (in SI or mks units), where r_o is the orbit radius. The name was chosen because the method was first applied to electrons. In the usual betatron both the accelerating core flux and a guiding magnetic field rise with similar time dependence, with the result that the orbit is circular. However, the orbit can have a changing radius as acceleration progresses. For the long path (usually more than 60 mi or 100 km), variations of axial and radial magnetic field components provide focusing forces, while space charge and space current forces due to the particle beam itself also contribute to the resulting betatron oscillations about the equilibrium orbit. In many other instances of particle beams, the term betatron oscillations is used for the particle oscillations about a beam's path.

Collective effects from self-fields of the beam have been found important and helpful in injecting. Circulating currents of about 3 amperes are contained in the numerous industrial and therapeutic betatrons, although the average currents are below 10^-7 A. See Particle accelerator

betatron

[′bād·ə‚trän] (nucleonics) A device for accelerating electrons in an evacuated ring by means of a time-varying magnetic flux encircled by the ring. Also known as rheotron.

betatron

A cyclotron which accelerates electrons via a pulsating magnetic field, imparting up to 20 MeV of energy. The first medical betatron was opened in the 1950s, but was limited by the low attainable strength of the magnetic field and the size of the magnetic core.
