Document Summary
Cyclotrons are used to accelerate charged particles including hydrogen ions, deuterium ions, and -particles. The particles are accelerated under vacuum by an electric field and are held in a spiral path by a magnetic field. The particle gains kinetic energy with each turn within the cyclotron until the maximum radius of trajectory is reached and therefore the maximum energy that the particle can achieve. Depending upon the design and size of the cyclotron, the energies achieved by the accelerated particle typically range from around 18 mev (mega electron volts) to about 70 mev. This range is typical for commercially available cyclotrons. In this section, we will look at irradiation of targets with a proton beam resulting from the acceleration of hydrogen ions to an energy of 18 mev. This method is typical of that used by cyclotrons for radioisotope production for diagnostic nuclear medicine. Figure 5: 18 mev cyclotron ( cyclone 18 twin", iba, belgium)
