betatron
a type of particle accelerator that uses the electric field induced by a varying magnetic field to accelerate electrons (beta particles) to high speeds in a circular orbit. The first successful betatron was completed in 1940 at the University of Illinois at Urbana-Champaign, under the direction of the American physicist Donald W. Kerst, who had deduced the detailed principles that govern the operation of such a device. Modern compact betatron designs are used to produce high-energy X-ray beams for a variety of applications
