The conceptual design of Rubbia et al. CERN/AT/95-44 (ET), 1995, for an acc
elerator driven system, known as the Energy Amplifier (EA), proposes use of
a spallation neutron source that is in turn induced by protons from a Cycl
otron or a Linac, in a subcritical array that makes use of liquid lead cool
ant. This paper introduces some qualitative changes to the concept of Rubbi
a et al. examining use of more than one point of spallation, in order to re
duce the requirements placed on proton energy and current of the accelerato
r, and specifically to obtain a flatter power density distribution. (C) 200
