Betatron Frequently Asked Questions

What is betatron accelerator?

The word betatron derives from the fact that high-energy electrons are often called β-particles. The betatron is a circular induction accelerator used for electron acceleration.

Who Invented the Betatron?

Betatron was invented by Donald W. Kerst in 1940 at the University of Illinois, Urbana-Champaign.

How Does a Betatron Work?

When an electric current is passed through the magnet, it generates a strong magnetic field inside the chamber. To accelerate the electrons, a series of alternating current (AC) pulses are sent through a coil located inside the chamber. These pulses create a rapidly changing magnetic field, which in turn induces an electric field. The electric field accelerates the electrons in a circular path within the chamber. As the electrons gain energy, their velocity increases, and they move in larger orbits. This process continues until the electrons reach their maximum speed or desired energy level.

What are the Different Types of Betatrons?

The different types of betatrons are classic betatron, resonant betatron, circular betatron and racetrack betatron

What are the parts of betatron?

The different parts of betatron are vacuum chamber, primary coil, injection system, detector and cooling system

What are the applications of betatron?

Betatrons are used to accelerate electrons, to produce gamma rays and x-rays, radiography and cancer treatment



Betatron

Betatron is a particle accelerator that is used to accelerate beta particles, usually electrons. It works on the principle of electromagnetic induction to accelerate charged particles to high energy particles. They were one of the earliest particle accelerator developed for research and development in the area of particle physics.

In this article, we will learn in detail about betatron, its construction, working principle, advantages, disadvantages, uses and limitations. We will also compare betatron with cyclotron in this article.

What is a Betatron?

Betatron is a circular induction accelerator used for electron acceleration. A betatron, utilized in high-energy physics, propels electrons to relativistic velocities. In other words, we can describe a betatron as a type of particle accelerator that produces high-energy electrons, or positrons. It operates on the principle of electromagnetic induction. It consists of a large toroidal vacuum chamber surrounded by an electromagnet. Alternating current (AC) is passed through the electromagnet, generating a time-varying magnetic field. Consequently, this field induces a voltage in a metal tube within the chamber, accelerating electrons to high energies as they spiral around the chamber due to the Lorentz force....

Oscillation in Betatron

The particles undergo oscillatory motion within the Betatron. Electrons move back and forth along their circular path as they gain energy. The oscillations are driven by the alternating magnetic field, which continuously accelerates the particles. The oscillation of the particle is in stable orbits. The motion of the particle is described by Hill’s equation which is given as...
