Abstract
The operability of a high power proton beam target in an Accelerator Driven System (ADS) is
strictly connected to the structural integrity of the beam window, which is undoubtedly the most
delicate component in such devices, being exposed to the combined effects of high intensity proton
and neutron irradiation, liquid metal corrosion and high thermal stresses induced by the interaction
with the beam. It has also recently been highlighted that beam trips may frequently occur in current
high power accelerators [1]. Clearly, the definition of the requirements of future accelerators depends
on the behaviour of the window under such conditions. For this purpose a numerical study of typical
transients has been carried out on the 600 MeV proton beam target that drives the 80 MW
Demonstration Facility of the Energy Amplifier proposed by C. Rubbia, [2] presently under
development in Italy by Ansaldo, CRS4, ENEA and INFN [3].
