Radionuclide Production
... Because neutrons are added, activated materials tend to lie above the line of stability, and thus to decay by electron emission Even in high neutron fluxes, only small amounts are activated, say 1:106109 For (n,γ) production, which is most common, the element does not change, so it is difficult to g ...

Motion of a charged particle in an EM field
... Figure 8: A banana orbit between two points on the high-field side of a tokamak [3]. While not obvious at first glance, magnetic mirrors can appear in tokamaks as well. Since the magnetic field lines, augmented by the poloidal field, now follow a helical trajectory in- and out-of the inner, high-fie ...

... A charged particle is moving perpendicular to a magnetic field in a circle with a radius r. An identical particle enters the field, with v perpendicular to B, but with a higher speed v than the first particle. Compared to the radius of the circle for the first particle, the radius of the circle for ...

Cyclotron
A cyclotron is a type of particle accelerator invented by Ernest O. Lawrence in 1932 in which charged particles accelerate outwards from the center along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field. Lawrence was awarded the 1939 Nobel prize in physics for this invention. Cyclotrons were the most powerful particle accelerator technology until the 1950s when they were superseded by the synchrotron, and are still used to produce particle beams in physics and nuclear medicine. The largest single magnet cyclotron was the 184 inch (4.6 meter) synchrocyclotron built between 1940 and 1946 by Lawrence at the University of California at Berkeley, which could accelerate protons to 730 MeV. The largest cyclotron is the 56 ft (18 meter) multimagnet TRIUMF accelerator at the University of British Columbia in Vancouver, British Columbia which can produce 500 MeV protons.
