Explain construction of cyclotron with diagram.

Explanation

1. Construction of cyclotron is as shown in diagram.

2. It consists of two small hollow, metallic half cylinders `D_(1)andD_(2)` called dees as they are in the shape of D.
3. They are mounted inside a vacuum chamber between the poles of a powerful electromagnet.
4.The dees are connected to the source of high frequency alternating voltage of few hundred kilovolts.
5. The beam of charged particles to be accelerated is injected into the dees near their centre P, in a plane perpendicular to the magnetic field.
6. The charged particles are pulled out of the dees by a deflecting plate which is negatively charged through a window W.
7. The whole device is in high vacuum so that air molecules may not collide with the charged particles.
