The SPIRAL 2 Preparatory Phase project aims to achieve the development and signing of the consortium agreement allowing for the construction of the facility. The SPIRAL 2 project located at the GANIL facility (Caen, France) will deliver energetic rare (radioactive) isotope beams with intensities not yet available with presently running machines. The studies of the properties of nuclei forming these beams or their interaction with stable nuclei is a rapidly developing field of contemporary nuclear physics, astrophysics and interdisciplinary research. Although the Region Basse-Normandie and the French funding agencies (CNRS and CEA) are financing the investment to the extend of 80% of the cost of baseline project, SPIRAL 2 seeks new partners in order to balance the construction budget both of the baseline project and of the new instrumentation necessary for experiments. The Preparatory Phase will deal with the critical financial, legal and organisational issues related to the international character of the SPIRAL 2 facility during its construction and operation phases. Searching for new funding partners will be achieved by direct contacts and negotiations between international partners, their funding agencies and the European Commission as established through the official visits, meetings and workshops. Several critical technical issues have still to be addressed in order to construct the SPIRAL2 facility and associated instrumentation. The corresponding tasks were chosen in order solve remaining technical challenges as well as to attract efficiently European partners. In particular, the accent was put on the new instrumentation for SPIRAL 2. This topic, being the most attractive for scientists, is an excellent tool to convince the funding agencies of international partners to commit for the construction phase. The attractiveness of SPIRAL 2 for outside users will be improved by the construction of new infrastructures.
