Polarization REsearch for Fusion Experiments and Reactors - The PREFER Collaboration: Purposes and Present Status

The possibility to exploit spin physics in fusion science opens new impressive panorama and challenging fields to be explored. In addition to the fundamental interesting topics the PREFER collaboration is trying with synergetic efforts to make the well known behaviour of spin–dependent nuclear reactions available for feasability studies and experimental tests for fusion programs. In this contribution the main challenges of the different collaborating groups will be put in evidence, and recent developments with the respective references will be provided.
