The accelerator and experimental facilities at GANIL (Caen, France) will be transformed over the next 5-10 years. At the heart of the new project, called SPIRAL-2, will be a new superconducting linear accelerator, which will act as a driver accelerator in order to provide with deuterons of 40 MeV (5mA; 200kW). With this primary beam a huge number of neutrons (~10e15 n/s) will be produced on a rotating carbon converter in the energy range between 1 keV and 40 MeV. As initially projected, intense high quality beams of neutron-rich nuclei, created in neutron-induced fission of the depleted uranium, will become available at SPIRAL-2. The facility is expected to be operational in 2009.
The main goal of this paper is to examine the possibility of using a linear deuteron accelerator in combination with the rotating target-converter for other purposes, namely,
a) neutron time-of-flight (nToF) measurements with pulsed neutron beams, and
b) material activation-irradiation with high-energy high-intensity neutron fluxes.
A number of case studies on the physics case with SPIRAL-2 neutrons will be presented.
