When a charged particle enter normal to a uniform magnetic field, it take a circular path. 

1. Name the particle accelerator using this principle. 

2. Explain the working of that particle accelerator with relevant theory.

3. The neutrons can’t be accelerated using this partide accelerator. Why?

1. Cyclotron.

2. Cyclotron:

a. Uses: It is a device used to accelerate particles to high energy.

b. Principles:

Cyclotron is based on two facts 

  • An electric field can accelerate a charged particle. 
  • A perpendicular magnetic field gives the ion a circular path

c. Working:

At certain instant, let D1 be positive and D2 be negative. Ion (+ve) will be accelerated towards D2 and describes a semicircular path (inside it). When the particle reaches the gap, D1 becomes negative and D2 becomes positive.

So ion is accelerated towards D1 and undergoes a circular motion with larger radius. This process repeats again and again. Thus ion comes near the edge of the dee with high K.E. This ion can be directed towards the target by a deflecting plate.

3. Charge of neutron is zero. Only charged particle can be accelerated using particle accelerated.
