A cyclotron is a type of particle accelerator invented by Ernest O. Lawrence in 1932. It is used to accelerate charged particles to high speeds using a combination of electric and magnetic fields. Here's how it works:

1. Electric Field: The cyclotron consists of two hollow "D" shaped metal containers called "dees" because of their shape. These dees are connected to an alternating current (AC) supply. When one dee is at a positive potential, the other is at a negative potential. This creates an electric field between the dees. A charged particle, such as a proton, is introduced at the center of the cyclotron. The electric field accelerates the particle from one dee to the other.

2. Magnetic Field: A strong magnetic field is applied perpendicular to the plane of the dees. This magnetic field causes the charged particle to move in a circular path. As the particle moves from one dee to the other, the polarity of the electric field changes due to the AC supply. This means that the particle is always accelerated as it crosses the gap between the dees.

3. Increasing Speed: The combination of the electric field (which accelerates the particle) and the magnetic field (which bends the particle into a circular path) allows the cyclotron to increase the speed of the particle with each revolution. The particle spirals outward from the center of the cyclotron, gaining speed with each revolution, until it reaches the edge of the cyclotron and is ejected as a high-speed particle beam.

In the case of the 1937 experiment at the University of California, the cyclotron was used to accelerate particles to high speeds and then collide them with a target to produce isotopes, such as the phosphorus isotope used in cancer treatment.
