Polarized ion sources and targets have been developed at RCNP, Osaka University. Based on this experience, we started the project of hyperpolarized nuclei for medical imaging with 3He and 19F by the brute force and PHIP (Parahydrogen Induced Polarization) methods, respectively [1]. Here, the latest development on the 3He hyperpolarization is presented, whereas the other parts will also be...

In the last two decades the intensity of polarized atomic beam sources sticks at about $10^{17}$ polarized atoms/s. Therefore, even the areal density of internal storage-cell targets for experiments like ANKE/COSY or PAX/COSY could not exceed $10^{14}$ atoms/cm$^2$. Even the use of openable storage cells or cooling of the cell walls could not help to overcome this limit. One possible option to...

Polarized $^3$He is of particular importance for fundamental research since the spins of the two protons
are oriented anti-parallel so that the nuclear spin is basically carried by the unpaired neutron. That
is why polarized $^3$He $^1$ can be used, for example, as an effective polarized neutron target for studying
the neutron structure by scattering with polarized electrons $^2$. For many...
