Cyclotron
The cyclotron is a device used to accelerate charged particles to high energies. It was designed by Lawrence
Principle
Cyclotron works on the principle that a charged particle moving normally with respect to a magnetic field experiences a magnetic Lorentz force due to which the particle moves in a circular path.
Functioning:
When a positive ion of charge q and mass m is emitted by the source, it is accelerated towards the Dee having a negative potential at that instant. Due to the normal magnetic field, the ion experiences a magnetic Lorentz force and moves in a circular path. As the ion arrives at the space between the Dees, the polarity of the Dees reverses. Therefore, the particle is accelerated again and moves towards the other Dee with greater speed along a circle of larger radius. Thus, the particle moves along a spiral path of increasing radius. The high energy particle is now allowed to reach the T target.
