Cyclotron

A device which accelerates charged particles in a vacuum thanks to the combined actions of an electrical field and a magnetic field. The magnetic field, applied perpendicularly to the speed of the particles, imposes a circular trajectory on these particles. The electrical field, caused by an alternating voltage between the machine’s two semi-circles, accelerates the particles each time they pass by in the space between the two semi circles. When a charged particle (proton, ion, etc.) is sent into the machine it starts to describe quicker and quicker and larger and larger radiuses up until the point it leaves the device to hit its target.
