[en] Scattering experiments with polarized nucleon targets are an important tool to understand the nuclear spin structure. Pion photoproduction experiments on polarized protrons and neutrons as well as measurements of the neutron and deuteron formfactors will be performed at ELSA. ⁷LiH and ⁶LiD seem to be attractive target materials for these experiments, because they offer high proton and deuteron polarisation, respectively. Expecially ⁶LiD has further very important advantages compared to the common deuteron target materials as d-Butanol and ND₃. This work describes the mechanism of DNP (Dynamic Nuclear Polarization) in LiH and LiD and gives a view on the nature of the so-called paramagnetic impurities in these materials. In order to maximize the nuclear polarization, the production of these radicals have to take place under well defined temperature conditions. Therefore the first version of an irradiation cryostat was built and tested in regard to its cooling power and temperature adjustment. (orig.)

[en] The polarization in polarized solid targets is usually measured by a continuous wave nuclear magnetic resonance system (CW-NMR). This technique reaches its limits for small and wide signals. The pulsed NMR technique is usually used in nuclear physics and medicine, because of its higher performance and sensitivity compared to the CW-NMR. First tests and linearity measurements of the detection system of our new pulsed NMR will be presented
