Abstract: The PREFER (Polarization REsearch for Fusion Experiments and Reactors) collaboration wasborn to address the know-how in different fields and techniques to the challenging bet on fusionenergy production with polarized fuel. Efforts are focused on a variety of tasks and objectives,which are under the responsibility of different institutes.Starting from open questions in the fusion reaction physics, such as the study of d-d spin-dependent cross sections to measurements of nuclear polarization conservation in laser-inducedfusion plasmas, there is still unexplored territory to discover. The collaboration aims to producenuclear-spin polarized molecules, recombined from polarized atomic beams, and their condensationand transport, or explore new a possibility by the resonance (“Sona”) transition technique whichpromises sufficient intensity for the feeding of fusion reactors.Other options of production are investigated, like nuclear-spin polarization of molecules by laseror microwave excitation. The presentation provides the status of proposals and investigations inthe European community.
