What is cyclotron?State its principle.
Answers
Answer:
Cyclotron is a device used to accelerate charged particles to high energies. It was devised by Lawrence. Cyclotron works on the principle that a charged particle moving normal to a magnetic field experiences magnetic lorentz force due to which the particle moves in a circular path.

Answer:
a cyclotron is machine which accelerates particles.It accelerates charged particles,outwards from the centre along a spiral path.
Explanation:
A cyclotron consists of two hollow semicircular electrodes, called dees, mounted back to back, separated by a narrow gap, in an evacuated chamber between the poles of a magnet. An electric field, alternating in polarity, is created in the gap by radio-frequency oscillator.
The particles to be accelerated are formed near the centre of the device in the gap, where the electric field propels them into one of the dees. There the magnetic field guides them in a semicircular path. By the time they return to the gap, the electric field has reversed, so they are accelerated into the other dee. Although the speed of the particles and the radius of their orbit increase each time they cross the gap, as long as the mass of the particles and the strength of the magnetic field remain constant, these crossings occur at a fixed frequency, to which the oscillator can be adjusted.
