Nonetheless, they are still widely used to produce particle beams for nuclear medicine and basic research. As of 2020, close to 1,500 cyclotrons were in use worldwide for the production of radionuclides for nuclear medicine. [10] In addition, cyclotrons can be used for particle therapy, where particle beams are directly applied to patients. [10]
Besides the real accelerators listed above, there are hypothetical accelerators often used as hypothetical examples or optimistic projects by particle physicists. Eloisatron (Eurasiatic Long Intersecting Storage Accelerator) was a project of INFN headed by Antonio Zichichi at the Ettore Majorana Foundation and Centre for Scientific Culture in ...
Fixed-field machines, such as cyclotrons and FFAs, use the former approach and allow the particle path to change with acceleration. In order to keep particles confined to a beam, some type of focusing is required. Small variations in the shape of the magnetic field, while maintaining the same overall field direction, are known as weak focusing.
The machines are used for the production of isotopes used in Positron emission tomography (PET), Single-photon emission computed tomography (SPECT) or production of technetium-99 for molecular imaging. [2] ACSI controls approximately half the world market for such machines, [2] Four models of cyclotrons are offered:

Cyclotrons have a single pair of hollow D-shaped plates to accelerate the particles and a single large dipole magnet to bend their path into a circular orbit. It is a characteristic property of charged particles in a uniform and constant magnetic field B that they orbit with a constant period, at a frequency called the cyclotron frequency , so ...
In particle physics, cyclotron radiation is electromagnetic radiation emitted by non-relativistic accelerating charged particles deflected by a magnetic field. [1] The Lorentz force on the particles acts perpendicular to both the magnetic field lines and the particles' motion through them, creating an acceleration of charged particles that causes them to emit radiation as a result of the ...
Cyclotrons accelerate protons at a target to produce positron-emitting radionuclides, e.g. fluorine-18. Radionuclide generators contain a parent radionuclide that decays to produce a radioactive daughter. The parent is usually produced in a nuclear reactor. A typical example is the technetium-99m generator used in nuclear medicine.
