Advantages of Nuclear Fusion with Polarized Fuel

The use of nuclear polarized fuel, i.e. polarized D, T or $^3$He, for coming fusion reactors promises to increase their energy output and to optimize the complete fusion process in various ways. But before these advantages can be utilized, several questions must be answered and technical issues must be overcome. Among others, the members of the PREFER collaboration started to investigate the different challenges of 'polarized fusion'.
