In scheme of coherent electron cooling*, a modulation of electron beam density induced by a co-propagation hadron is amplified in high gain FEL. The resulting amplified modulation of electron beam, its shape, form and its lethargy determine number of important properties of the coherent electron cooling. In this talk we present both analytical and numerical (using codes RON and Genesis) evaluations of the corresponding Green functions. We also discuss influence of electron beam parameters on the FEL response.

Cooling intense high-energy hadron beams remains a major challenge for accelerator physics. Synchrotron radiation is too feeble, while efficiency of two other cooling methods falls rapidly either at high bunch intensities (i.e. stochastic cooling of protons) or at high energies (i.e. e-cooling). Possibility of coherent electron cooling based on high-gain FEL and ERL was presented at last FEL conference*. This scheme promises significant increases in luminosities of modern high-energy hadron and electron-hadron colliders, such as LHC and eRHIC. In this talk we present progress in development of this concept, results of analytical and numerical evaluation of the concept as well our prediction for LHC and RHIC. We also present our plan and design for proof-of-principle experiment at RHIC using existing R&D ERL.
