Among the accelerator-based neutron sources, the ones which are driven by electron Linacs still appear quite attractive, notably in the case of cross section measurements with the time-of-flight method. This is due to their better beam quality and economy aspects, which make them complementary, rather than inferior to the hadron (protons, deuterons) driven spallation facilities.A conceptual design study of a powerful neutron source has been developed, aiming at the implementation on a future normal- or super-conducting Linac to be built in the Rome Research Area, but keeping enough flexibility for being installed on any high energy linac. We report in this paper on the first simulation results, mainly about the general design of the target-moderator assembly and the radiation shielding.
