Lawrence's inspiration was to reconfigure Wideröe's cylinders as D-shaped chambers and position them between the poles of a magnet.
Later, Lawrence used improved versions of the cyclotron to investigate nuclear processes and to produce a variety of new and medically important isotopes (e.g., the phosphorus-32 used in early attempts to treat leukemia).

 History
In 1929 Ernest O. Lawrence came up with a new technique to accelerate a particle, with the help of a article by a Norwegian engineer, Rolf Wideröe.
The idea was that particles with a positive electric charge are drawn into the first cylindrical electrode by a negative potential; by the time they emerge from the tube the potential has switched to positive, which propels them away from the electrode with a second boost.
Lawrence's cyclotron was effective, but could never reach the energies that our modern day circular accelerators do.
