Electron cooling for positron sources
Physical Review Letters, 1988Electron cooling of positrons should make possible a large increase in the luminosity of future high-energy linear colliders, leading to greatly enhanced event rates at these machines. An evaluation of the electron-cooling-time requirement indicates that a positron-source repetition rate of 100 Hz is possible.

Abstract This article deals with the relaxation of a positron beam in electron gas moving in a magnetic field. A situation is considered where the electron longitudinal temperature is lower than the transverse one. Expressions for the friction force and scattering coefficients of positron momenta have been found, with plasma shielding taken into ...

Currently, there is a worldwide boom of plans and proposals for heavy-ion storage rings with beam cooling. This boom has three main reasons: 1. Many heavy-ion accelerators are operating successfully all over the world; thus, a lot of experience in design, construction, and operation of such accelerators is available; 2.

Abstract Electron cooling of completely stripped gold ions 197 Au 79+ in RHIC is considered for the store energy, γ =108. The optimal parameters of the required electron storage ring are discussed and proposed. The cooling time is calculated as 15 min, which would allow not only to avoid the beam loss due to the intra-beam scattering,

The design of the CRYRING electron cooler, including magnets, electron gun and collector, and the vacuum system, is described. Light and heavy atomic ions and molecular ions have been cooled at ion energies between 0.29 and 10.9 MeV per nucleon. Experiments in atomic and molecular physics have been performed using the cooler both for beam cooling and ...

There are two simple measures of the temperature of a solid: the electron temperature and the temperature of the atoms or, more precisely, the lattice vibrations or "phonons". Both temperatures are generally assumed to be the same. Sometimes the electron temperature is higher – in high-electron-mobility semiconductors, for example.
