The cyclotron consists of two dees in strong magnetic field where oscillating electric field is applied from an oscillator. In this, magnetic field is perpendicular to electric field which exists only across the gap between the dees. The charged particle gets accelerated, while crossing the gap and moves along the circular paths with radius r…
