The development, in the early 1960s, of the dynamic nuclear polarization scheme in solid diamagnetic materials, doped with paramagnetic radicals, led to the use of solid polarized H and D targets in numerous nuclear and particle physics experiments. Since then steady progress has been made in all contributing sub-systems so that proton polarization values around 90% and deuteron polarization values between 40% and 80% have been achieved in various set-ups. These polarization values have been measured with a relative accuracy of {+-}5% or better using nuclear magnetic resonance techniques. Many experiments with reasonably high luminosities have taken advantage of these developments and many more are being planned, especially with electromagnetic probes. Latest developments open up the possibility to use DNP hyperpolarized substances for medical applications.
