Diagram of cyclotron operation from Lawrence's 1934 patent. The hollow, open-faced D-shaped electrodes (left), known as dees, are enclosed in a flat vacuum chamber which is installed in a narrow gap between the two poles of a large magnet (right). Vacuum chamber of Lawrence 69 cm (27 in) 1932 cyclotron with cover removed, showing the dees.

Description: 60-inch cyclotron, 1939. This shows the cyclotron at the Lawrence Radiation Laboratory, Berkeley, soon after completion in 1939. The key figures in its development and use are shown, standing, left to right: Dr D Cooksey, Dr D Corson, Dr Ernest Orlando Lawrence (1901-58), the inventor of the cyclotron; Dr R Thornton, Dr J Backus, WS Sainsbury [W. W. Salisbury], Dr LW Alvarez (1911 ...
Diagram of a cyclotron orbit of a particle with speed v, which is the classical trajectory of a charged particle (here positive charge) under a uniform magnetic field B. The Landau quantization refers to a quantum charged particle under a uniform magnetic field.
Diagram of cyclotron operation from Lawrence's 1934 patent.. While the principle of the cyclotron to create a two-dimensional array of electrons has existed since 1934, the tool was originally not really used to analyze interactions among the electrons (e.g. two-dimensional gas dynamics).
A synchrocyclotron is a special type of cyclotron, patented by Edwin McMillan in 1952, in which the frequency of the driving RF electric field is varied to compensate for relativistic effects as the particles' velocity begins to approach the speed of light. This is in contrast to the classical cyclotron, where this frequency is constant. [1]
Diagram of cyclotron operation from Lawrence's 1934 patent. Lawrence saw that such a particle accelerator would soon become too long and unwieldy for his university laboratory. In pondering a way to make the accelerator more compact, Lawrence decided to set a circular accelerating chamber between the poles of an electromagnet.
Diagram of a cyclotron orbit of a particle with speed v, which is the classical trajectory of a charged particle (here positive charge) under a uniform magnetic field B. Cyclotron resonance describes the interaction of external forces with charged particles experiencing a magnetic field , thus moving on a circular path.
