High energy cooling

The paper considers methods of particle cooling mostly concentrating on cooling of high energy heavy particles in the high energy colliders. Presently, there are two major methods of the cooling the electron cooling and stochastic cooling. The latter can be additionally separated on the microwave stochastic cooling, the optical stochastic cooling (OSC) and the coherent electron cooling (CEC). OSC and CEC are essentially extensions of microwave stochastic cooling operating in 1-10 GHz frequency range to the optical frequencies corresponding to 30-300 THz frequency range. The OSC uses undulators as a pickup and a kicker, and an optical amplifier for signal amplification, while the CEC uses an electron beam for all these functions

Multiple intrabeam scattering in X-Y coupled focusing systrems

This paper describes an analytical theory to calculate the emittance growth rates due to intrabeam scattering in focusing systems with arbitrary x-y coupling. The presented results are based on calculations of average emittance growth rates for an initially Gaussian distribution
