Useful formulas for non-magnetized electron cooling

  title={Useful formulas for non-magnetized electron cooling},
  author={Sergei Seletskiy and Alexei Fedotov},
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
Theory of Electron Cooling in Accelerators
Momentum, energy and emittance relaxation processes of the ions have been theoretically studied on the electron cooling in accelerators when the solenoid magnetic field and the space charge of the
An effective method of damping particle oscillations in proton and antiproton storage rings
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
Experimental Demonstration of Hadron Beam Cooling Using Radio-Frequency Accelerated Electron Bunches.
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.
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
