ELFE@DESY: Slow extraction from HERA
Abstract
The ELFE project (Electron Laboratory For Europe) proposes a 15-25 GeV, 30 μA c.w. electron beam for nuclear physics experiments. It seems feasible to integrate such a laboratory into a linear collider facility at DESY by using the HERA electron ring as a stretcher for the short pulses of a collider linac. The pulses can be stretched to a quasi continuous beam by making use of slow resonant extraction, as is successfully realized at lower energies at several other facilities. The necessary modifications of the HERA electron ring have been investigated by an international study group. The proposed beam optics for resonant extraction as well as the achievable performance determined by tracking studies and analytic calculations are presented.
