The results of the recently completed study for the European Spallation Neutron Source (ESS) demonstrated the feasibility of a pulsed 5 MW source and identified the topics where further R & D is required. The highest priority was assigned to target issues, because the proposed liquid mercury target breaks new ground in target physics and technology. The anticipated joint R & D in this novel field comprises (details in TOP 2 of prop. descript.)
(1) Structural Materials: Radiation damage and stress pulses (2) Radiation Physics: Neutron production, radiation fields, cross sections for radiation damage processes, optimisation of utilisable
(3) Fluid Dynamics: Mitigation of pressure pulses; flow patterns and heat transfer
(4) Target Engineering: Layout and design of high power proton targets; cold methane moderators; construction and operation of test facilities In order to achieve optimum progress in these four interconnected areas, research teams in the institutions listed on p. 42 have agreed to combine their special know-how and available resources. The
scientific-technological goal of the common work to be carried out in the 3-years period of the proposed network is:
To provide the necessary data base and engineering requirements for a detailed technical design of a 5 MW target station for ESS with optimum performance, reliability, lifetime and safety of its components.
Besides providing the research teams with 'fresh blood', the hiring of young researchers via the TMR Programme opens the opportunity for training (details in TOP 10 of prop. descript.). This is beneficial for (1) improving the qualifications of the individual researchers (and thus promoting their professional carrier) by working in fields which are inter-linked with many different other topics and methods in a complex way and (2) building up a European team of young scientists and engineers who will be able to lead the design and construction and, finally, to carry out and optimise the operation of ESS for the international users community. To achieve both the scientific and the training goals is a necessary condition for maintaining Europe's leading position in the fields of intense neutron sources and of neutron scattering.
