High energy electron cooling to improve the luminosity and lifetime in colliding beam machines
Electron cooling can be applied to improve the performance of high energy colliding beams of hadrons and e/sup -/p storage rings. Normal beam excitations such as multiple scattering, resonance growth, or beam--beam interaction can be controlled, leading to longer beam lifetimes, and in some situations to higher luminosities and larger tolerable tune shifts. The electrons, in a small storage ring, are cooled by radiation and heated by the hadron beam. An equilibrium is reached in which the hadron beam is cooled. The electron beam requires strong cooling by wigglers. A simple cooling experiment for the Fermilab synchrotron is described. Relativistic proton or antiproton beams in circular accelerators or storage rings can be damped by interactions with electrons (..gamma../sub p/ = ..gamma../sub c/) circulating in a storage ring. The proton or antiproton beam is damped and the electron beam is heated in the interaction. In order to reduce the blowup of the electron beam, synchrotron radiation in bending magnets or wiggler magnets and subsequent acceleration in an rf system is required, thus the electron beam is cooled.
