What is cycloctron?

Answer 1

It's a device used to accelerate charged particles.

The device is circular, so the path of the particles is also,

and each time a particle goes around the circle it is forced to go faster.

Answer 2

A cyclotron is a type of particle accelerator that uses a combination of electric and magnetic fields to accelerate charged particles, typically protons or electrons, in a spiral path. The particles gain energy as they travel in a circular or spiral trajectory until they reach the desired speed for various applications such as medical imaging or nuclear physics research.
