New proposal for the fast energy amplifier

The conceptual design of Rubbia et al. CERN/ AT/ 95-44 (ET), 1995, for an accelerator driven system, known as the Energy Amplifier (EA), proposes use of a spallation neutron source that is in turn induced by protons from a Cyclotron or a Linac, in a subcritical array that makes use of liquid lead coolant. This paper introduces some qualitative changes to the concept of Rubbia et al. examining use of more than one point of spallation, in order to reduce the requirements placed on proton energy and current of the accelerator, and specifically to obtain a flatter power density distribution.
