However, current methods are limited in achievable intensity or polarization and require complex sources.Our new approach promises to overcome these limitations with an intense polarized $^3$He beam with a polarization up to 𝑃 ∼ 0.9. The method is theoretically well understood and uses single radio wave pulses to induce transitions within the hyperfine structure in the Zeeman region of $^3$He$^+$. In this way, the three substates of the 𝐹 = 1 triplet can be pumped into a single one, leading to a nuclear polarization. Experimentally, the achievable polarization is planned to be measured after acceleration of the $^3$He ions with the cyclotron JULIC using the known analyzing powers of the elastic scattering on protons in the 10–100 MeV energy range.
