It is a device developed by Lawrence and Livingstone and is used to accelerate charged particles like protons and deuterons. This results in the production of high energy beam which is then used for artificial disintegration, etc.

It consists of two D shaped metal boxes (about 21″ in diameter) with their straight sides facing each other. There is a very small gap between these Dee’s faces across which a high potential difference (of an order of 105 volts) is applied by a high frequency (10-15 megacycles per second) oscillator. Thus an alternating electric field is established between Dee’s during a one-half cycle, one dee is positive and the other is negative while during the next half cycle, the other is positive and one is negative. A source of the particle (heavy hydrogen for producing deuterons) is placed between the faces. The whole apparatus is placed between the pole pieces NS of a very strong magnet.

In this video #Cyclotron for the #class12 is discussed. To understand the working of #Cyclotron understanding of the #Lorentz force is important. In the first part of this video, the basic idea of Lorentz force is discussed.

The #Electric force is responsible to accelerate the particle while no contribution of the # Magnetic force except to change in the direction. The #velocity does not affect by the magnetic force. In a uniform magnetic field (same magnitude everywhere of the magnetic field in a specified area.) when a moving #charge particle enters it realize a force which acts as a centripetal force and hence a circular motion. The direction of the force can be found with the help of #Fleming’s left-hand rule, where the thumb represents the direction of #force, first finger direction of the magnetic field and middle to the direction of the velocity of the moving charged particle.
