Specification of a new electron cooler for the low energy ion accumulator ring, LEIR

For the cooling of Pb54+ ions in the future low-energy ion ring machine a new electron cooling device needs to be constructed. This new cooler will take advantage of all the recent developments in electron cooling in order to balance efficient and fast cooling with a sufficiently long ion beam lifetime for beam accumulation. This paper will present the special features of the device and how their combination will be used to obtain low emittance beams for transfer to the LHC.
