A European proposal is under preparation for the Compton gamma-ray Source of ELI-NP.In the Romanian pillar of ELI (the European Extreme Light Infrastructure) an advancedgamma-ray beam is foreseen, coupled to two 10 PW laser systems. The photons will begenerated by Compton back-scattering in the collision between a high quality electron beamand a high power laser. A European collaboration formed by INFN, Univ. of Roma La Sapienza,Orsay-LAL of IN2P3, Univ. de Paris Sud XI and ASTeC at Daresbury, is preparing a TDRexploring the feasibility of a machine expected to achieve the Gamma-ray beamspecifications: energy tunable between 1 and 20 MeV, narrow bandwidth (0.3%) and highspectral density, 104 photons/sec/eV. We will describe the lay-out of the 720MeV RF Linac and the collision laser with the associated optical cavity, as well as theoptimized beam dynamics to achieve maximum phase space density at the collision. Thepredicted gamma-ray spectra have been evaluated for the case at 360 MeV. Copyright ©2012 by IEEE.
