MSH: Devices for accelerating protons or electrons in closed orbits where the accelerating voltage and magnetic field strength varies (the accelerating voltage is held constant for electrons) in order to keep the orbit radius constant.,NCI: A device that accelerates particles in a circular orbit at a fixed radius. The acceleration is performed in an increasing magnetic field by means of an alternating electric field applied in conjunction with the orbital motion. This device has been utilized to delineate the structure of proteins involved in a variety of cancers and diseases.,CSP: device for accelerating protons or electrons in closed orbits where the accelerating voltage and magnetic field strength varies (the accelerating voltage is held constant for electrons) in order to keep the orbit radius constant; the radiation produced can be used to investigate objects of atomic and molecular size.
