Particle beam cooling

Particle beam cooling is the process of improving the quality of particle beams produced by particle accelerators, by reducing the emittance. Techniques for particle beam cooling include:^[1]

• Stochastic cooling^[2]
• Electron cooling^[3][4]
• Ionization cooling
• Laser cooling^[5]
• Radiation damping
• Buffer-gas cooling within RF quadrupoles
