 Particle beam cooling

Particle beam cooling refers to various techniques used to reduce the temperature (and therefore the spread in energy) of a beam of charged particles, such as electrons or protons. The main objective of these cooling methods is to enhance the beam quality by decreasing its emittance, which is a measure of the spread of particle positions and momenta. This is particularly important in high-energy particle accelerators and storage rings to achieve higher luminosity, which is essential for various scientific experiments, including those in particle physics.
