Solution
The correct options are A Cyclotron B Synchroton D Linear accelerator Particle accelerators were invented to investigate small size objects. The great breakthrough in accelerator technology came in 1920 with Ernest O. Lawrence's invention of the cyclotron. In the cyclotron, magnets guide the particles along a spiral path, allowing a single electric field to apply many cycles of acceleration. Soon unprecedented energies were achieved, and the steady improvement of Lawrence's simple machine has led to today's proton synchrotrons, whose endless circular flight paths allow protons to gain huge energies by passing millions of times through the electric fields that accelerate them. Presently, particle accelerators are cyclotrons, synchrotrons, and linear accelerators.
