WebPET radioisotopes are produced in cyclotrons. A cyclotron is a particle accelerator (see Note 3). It is an electrically powered machine which produces charged particles in an ion chamber in the centre of the machine. As the name suggests, a cyclotron accelerates the beam of charged particles in a spiral path. WebParticles accelerated in a large synchrotron are commonly injected by a linear accelerator and are steered into the ring by a device called an inflector. They begin their acceleration in the ring when the magnetic field is small.

WebCyclotrons consist of evacuated cylinder divided into two sections referred to as "Dees" (because they look like a capital D). The evacuated cylinder is placed between two large magnets producing a constant magnetic field. Charged particles are injected into the center of the cylinder and an oscillating electric field is applied to the Dees. Web16 de fev. de 2024 · Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B. The first term is contributed by the electric field. …
