The cyclotron is a device that can accelerate sub-atomic particles to a very high speed for particle experiments and clinical needs. It energizes particles, sending them through an alternating electric and a constant magnetic field. The cyclotron was invented by E. O. Lawrence and others. This app demonstrates the working of the cyclotron based on the Lawrence force equation. A set of graphs helps to investigate the concepts further. Users can change the variables in the equation and study the behavior. An excellent tool for physics students and teachers. A Windows 11 desktop application.
