	The low temperature of the electron beam is the key for the high efficiency of the electron cooling, and the strong guiding magnetic field is the means for it. However, high-voltage electron cooling systems come with the challenge of providing the low-temperature beams, as the guiding magnetic field is limited.

TUY01	RF Accelerator for Electron Cooling of Ultrarelativistic Hadrons	26
	N.A. Vinokurov, V.V. Parkhomchuk, A.N. Skrinsky BINP SB RAS, Novosibirsk, Russia N.A. Vinokurov NSU, Novosibirsk, Russia
	New projects of high-energy hadron colliders could be improved significantly using electron cooling technique. But the source of high-current relativistic electron beam appears to be a technical challenge. Indeed, intrinsic energy limitations of high-voltage DC accelerators lead to necessity to use not static, but vortex, electrical field for acceleration. Induction and radiofrequency (RF) accelerators just use such field. Moreover, to keep small enough damping times at high energies, it needs to increase electron peak current to tens of amperes. The feasibility of RF energy recovery linac (ERL) for electron cooling is discussed. The ERL of the Novosibirsk free electron laser facility is used as a reliable prototype.
