The magnetic field makes the charge to move in the circular path and alternating electric field accelerates the charged particles. T is independent of speed of the charged particle. Cyclotron cannot accelerate (a) Electrons (b) Neutrons (c) Positive ions Ion Orbital Rotation Frequency- numerically Consider an arbitrary positive ion of atomic species (A,Z) with Q orbital electrons removed. The cyclotron is a particle accelerator which is also known as Lawrence cyclotron, As it was conceived by Lawrence in 1929. 1. Uncharged particles cannot be accelerated by a cyclotron. Hence frequency of revolution of the particle will be.

The revolution frequency, called the cyclotron frequency, is proportional to the charge q and the magnetic field, B, and inversely proportional to the particle mass, m : (3.1) (for a proton in a 1 T magnetic field, f ~ 15 MHz). Applied to anything that moves faster than sound (1,100 ft.p.s.
