Cyclotron

A cyclotron accelerates charged particles with a high-frequency, alternating voltage (potential difference). A perpendicular magnetic field causes the particles to go almost in a circle. The beam spirals out to the edge of the container, as the particles' speeds increase. At this point, the particles' speed approaches the speed of light.

The cyclotron was invented by Ernest Lawrence of the University of California, in 1929. He used it in experiments that required particles with energy of up to 1 MeV. Cyclotrons are used today to treat cancer. The bright, adjustable-frequency x-rays produced by a cyclotron's radiation can be adjusted to penetrate limited distances into the human body, in order to kill tumor cells.

Voltage: The voltage between two points is a short name for the electrical force that would drive an electric current between those points. Specifically, voltage is equal to energy per unit charge. In the case of static electric fields, the voltage between two points is equal to the change in electrical pote...
