| Parts & Accessories | The basic parts of the cyclotron are the magnetic system, vacuum sealed de-chambers, the oscillating power system, the ion injector, and the extraction system. |
| Operation | • A cyclotron accelerates a beam of charged particles using a high-frequency alternating voltage applied between two hollow D-shaped metal electrodes known as "plates" inside a vacuum chamber. • The machine is placed face-to-face with a narrow gap between them, creating a cylindrical space inside for the particles to move. The particles are injected into the center of this space. • Dees are located between the poles of an electromagnet that applies a constant magnetic field perpendicular to the plane of the electrode. • The magnetic field causes the particle's path to bend in a circle due to the Lorentz force perpendicular to the direction of its motion. • An alternating voltage of several thousand volts is applied between the machine. The voltage creates an oscillating electric field in the gap between the machine that accelerates the particles. • The frequency of the voltage is adjusted so that the particles do one circuit during one cycle of the voltage. To achieve this condition, the frequency must be set to the cyclotron frequency of the particle.  |
