Cyclotron is a device used to accelerate charged bodies to very high velocities (or high kinetic energies) using crossed (or mutually perpendicular) electric and magnetic fields Cyclotron is based on the independency of frequency (of rotation of charged particle) on the energy (velocity) and radius (of revolution) of charged particle. The Cyclotron Institute is a major accelerator facility, jointly funded by the State of Texas and the Department of Energy, that carries out a program of basic research and education in both nuclear physics and nuclear chemistry. A cyclotron consists of two D-shaped regions known as dees. The Cyclotron Institutes annual report for 2020-2021, Progress in Research, is now available. When a strong magnetic field created by two large electromagnets applies to these charged particles, they accelerate and reach a very high speed due to the electromagnetic field. Essentially, the process can be broken down into four parts: What is cyclotron frequency formula?
