In particle accelerators, magnetic and electric fields are employed to separate different subatomic particles.
Magnetic fields are used to bend the paths of charged particles. These magnetic fields are created either by permanent magnets or by electromagnets. By adjusting the strength and direction of the magnetic field, specific charged particles can be directed along different paths, allowing for their separation.
Electric fields, on the other hand, exert forces on charged particles. These fields are created using electrically charged plates or electrodes. By applying different electric potentials across these plates, particles with different charges can be diverted onto different paths, separating them based on their charge-to-mass ratios.
The characteristics that the particles need to have in order to be separated are primarily related to their charge and mass. Since the fields utilized in particle accelerators interact with charged particles, the particles of interest need to carry an electric charge. Additionally, the particles should have enough mass to experience a noticeable deflection or deviation when subjected to the magnetic or electric fields. Therefore, lighter particles such as electrons may require higher magnetic or electric field strengths to achieve separation compared to heavier particles like protons or ions.
