Consideration of Relativistic Dynamics in High-Energy Electron Coolers / Bruhwiler, David L ; Bell, George I
A proposed electron cooler for RHIC would use ~55 MeV electrons to cool fully-ionized 100 GeV/nucleon gold ions.* At two locations in the collider ring, the electrons and ions will co-propagate for ~13 m, with velocities close to c and gamma>100. To lowest-order, one can Lorentz transform all physical quantities into the beam frame and calculate the dynamical friction forces assuming a nonrelativisitc, electrostatic plasma. [...]

The Effect of Magnetic Field Errors on Dynamical Friction in Electron Coolers / Bruhwiler, David L ; Abell, Dan T ; Busby, Richard ; Fedotov, Alexei V ; Litvinenko, Vladimir N ; Veitzer, Seth A
A proposed luminosity upgrade to the Relativistic Heavy Ion Collider (RHIC) includes a novel electron cooling section,* which would use ~55 MeV electrons to cool fully-ionized 100 GeV/nucleon gold ions. A strong (1-5 T) solenoidal field will be used to magnetize the electrons and thus enhance the dynamical friction force on the ions. [...]

LEIR electron cooler status / Tranquille, G ; Bubley, A ; Parkhomchuk, V ; Prieto, V ; Sautier, R
The electron cooler for LEIR is the first of a new generation of coolers being commissioned for fast phase space cooling of ion beams in storage rings. It is a stateof- the-art cooler incorporating all the recent developments in electron cooling technology (adiabatic expansion, electrostatic bend, variable density electron beam) and is designed to deliver up to 600 mA of electron current for the cooling and stacking of Pb54+ ions in the frame of the ions for LHC project.

Review of recent work on electron cooling at LEAR / Bosser, Jacques (CERN) /CERN LEAR Team ; Russian Collaboration
The Low-Energy Antiproton Ring (LEAR) is expected to be used as an accumulator in the frame work of the LHC lead-ion project. This implies at first that the electron-cooled ions have a lifetime which is longer than the stacking time. [...]

Numerical Studies of the Friction Force for the RHIC Electron Cooler / Fedotov, Alexei V ; Abell, Dan T ; Ben-Zvi, Ilan ; Bruhwiler, David L ; Busby, Richard ; Litvinenko, Vladimir N ; Schoessow, Paul
Accurate calculation of electron cooling times requires an accurate description of the dynamical friction force. The proposed RHIC cooler will require ~55 MeV electrons, which must be obtained from an RF linac, leading to very high transverse electron temperatures. [...]

Heavy-Ion Beam Dynamics in the RIA Post-Accelerator / Ostroumov, Peter ; Aseev, Vladislav N ; Kolomiets, Andrej
The RIB linac includes two strippers for the heaviest ions and three main sections: a room temperature injector up to an energy of ~100 keV/u, a superconducting (SC) linac for ions with charge-to-mass ratio 1/66 or more up to an energy of ~1 MeV and a higher energy SC linac to produce 10 MeV/u beams up to the mass of uranium. The RIA post-accelerator is a complex system designed for acceleration singly-charged ions before the stripper and includes many different accelerating and focusing structures operating both at room and cryogenic temperatures.

Electron Cooling Simulation Benchmarking / Veglia, Bianca (Cockcroft Inst. Accel. Sci. Tech.) ; Biancacci, Nicolo (CERN) ; Gamba, Davide (CERN) ; Latina, Andrea (CERN) ; Resta-López, Javier (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Saá Hernández, Angela (CERN) ; Welsch, Carsten (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.)
Electron coolers are commonly used in storage rings to reduce the phase space volume of heavy particles such as protons, antiprotons and ions. Their effect depends on the Coulomb interactions between the circulating beam and the cold electrons at small relative velocities. [...]
