Recent success of Low Energy RHIC Electron Cooler (LEReC) opened a road for development of high energy electron coolers based on non-magnetized electron bunches accelerated by RF cavities. Electrons in such coolers can have velocity distribution with various unequal horizontal, vertical and longitudinal velocity spreads. In this paper we revisit a formula of friction force in non-magnetized cooling and derive a number of useful expressions for different limiting cases.

Theory of electron cooling
We consider the process of cooling of a heavy particle beam in a co-moving electron beam of low temperature guided by a solenoidal magnetic field. This paper summarizes the main results of

A method is proposed for the damping of synchrotron and betatron oscillations of heavy particles, which makes use of the sharp increase in the cross section for the interaction of these particles

TLDR
The first demonstration of cooling hadron beams using this new approach to bunched-beam cooling at higher energies than possible with electrostatic acceleration of electron beams is reported on.
THE EFFECT OF AN ACCOMPANYING MAGNETIC FIELD ON ELECTRON COOLING
We consider the cooling of a beam of heavy particles in an accompanying electron flux "frozen" by a longitudinal magnetic field. The velocity distribution of electrons is assumed to be sharply
Obtaining transverse cooling with nonmagnetized electron beam
The first electron cooling with rf-accelerated electron bunches was recently demonstrated at the low energy RHIC electron cooler (LEReC) at BNL. Successful cooling requires that the electrons in the
Effects of coherent offset of velocity distribution in electron coolers on ion dynamics
We revisit the effect of coherent offset in velocity distribution of the electron beam in electron coolers and consider its implications for the dynamics of the cooled ion bunch. This effect becomes
