Betatron Oscillations

Definition

Betatron oscillations refer to the oscillatory motion of charged particles in a magnetic field as they are accelerated in a betatron, which is a type of particle accelerator. These oscillations are crucial for the effective focusing and control of the particles' paths within the accelerator, ensuring that they maintain their intended trajectory while gaining energy from the changing magnetic fields.
