Principal characteristics of the facility and of the support offered to users:
The KVI is the Dutch centre for nuclear-physics research. The institute is funded by the University of Groningen and the National Science Foundation FOM. The central facility of the institute is the superconducting cyclotron AGOR, which started operation in the summer of 1996. AGOR is capable of accelerating both light and heavy ions. There are two major experimental equipments in combination with AGOR: a big-bite magnetic spectrometer (BBS) . and a small-angle large-acceptance detector for measuring protons and other light particles (SALAD). At the . moment, the AGOR facility is a unique facility in Europe in its combination of delivering external polarised proton and deuteron beams in the range of 90 to 200 MeV and the possibility to detect these in a broad-range spectrometer . (BBS) with a polarimeter allowing for spin-transfer measurements in the nuclear continuum.
The underlying physics of light-ion scattering processes requires a systematic study over a large bombarding energy range and the use of different types of equipment. The joint three facilities in this proposal (AGOR in Groningen, CELSIUS in Uppsala, and COSY in Juelich) will provide (polarised) protons in the energy range from 50 to 2500 MeV and light ions from 10 to 470 MeV/amu, and will allow for the exchange of sophisticated equipment. These three facilities will form the Light-Ion Facility Europe (LIFE) which will have a unique position in Europe and a strongly competitive position in the world.
External users under the TMR contract will be given full access to all (experimental) facilities as well as full support from the local staff, provided their experiment has been approved by the local Programme Advisory Committee.
Quantity of access being offered and number of users who may benefit: This proposal seeks to extend the planned beam time on target of 3000 hours per year by an additional 20%, earmarked for experiments with light-ion beams. The total access offered to new users of the AGOR facility under the TMR programme will be 1800 hours beam on target or 75 24-hour days during three years. This means that 135 extra users will be able to participate in approximately 15 different projects.
