Built by Lawrence in 1929
Accelerates positive particles rather than the electrons
Uses positively charged particles such as proton, neutron, alphas, deuterons, short- lived radioisotopes
Particles are accelerated in a circular chamber called dees
The particles are accelerated by electric fields between the dees until the particle acquires the desired energy
Powerful magnetic filed are employed to confine the particle [...]
