Since the discovery of nuclear spin, scientific efforts have been focused on the production of non-equilibrium spin distributions, in which one of the possible spin projections prevails. Nuclear spin-polarization is advantageous for several fields of scientific (physics, chemistry, biology) and public (medicine) interest. Recently, our group developed a new polarization method based on radio-wave pumping at small magnetic fields that can be applied to particle beams and potentially to samples. Its advantages compared to conventional methods along with its limitations will be highlighted. Some exemplary applications are polarized sources and targets for the measurement of spin-dependent observables, polarized nuclear fusion, medical imaging diagnostics, etc.. Further developments and our future plans will be discussed.
