- Electron cooling
Electroncooling is a process to shrink the size, divergence, and energy spread of charged particle beamswithout removing particles from the beam. Since the number of particles remains unchanged and the space coordinates and their derivatives (angles) are reduced, this means that the phase spaceoccupied by the stored particles is compressed. It is equivalent to reducing the temperature of the beam. See also stochastic cooling.
It was invented by G.I. Budker (INP, Novosibirsk) in
1966as a way to increase luminosity of hadron colliders. It was first tested in 1974with 68 MeV protons at NAP-M storage ring at INP.
Basically, electron cooling works as follows:
velocityof the electrons is made equal to the average velocity of the ions.
* The ions undergo Coulomb scattering in the electron “gas” and lose energy, which is transferred from the ions to the co-streaming electrons until some thermal equilibrium is attained.
