Question

Explain the term betatron.

Answer 1

Step 1: Definition of Betatron

1. A betatron is an instrument that is used to accelerate electrons or beta particles under the influence of an electric field induced by a varying magnetic field.
2. It accelerates the beta particles to a great speed in a circular orbit.

Step 2: Applications of betatron

1. High energy electron beam.
2. Produce X-rays and gamma rays.
3. Used in industrial and medical fields.
4. Used in particle physics.

Step 3: Limitations of betatron

1. The saturation of iron and the size of the magnetic core limit the maximum magnetic field and energy range imparted by it to electrons.
2. The electric field cannot be varied.
