Research and Development of the Polarized Deuteron Source for the Van de Graaff Accelerator

An attempt is made to develop a polarized deuteron source suited for the Van de Graaff accelerator of Czech Technical University in Prague. We based on Kaminsky’s experiment on channeling deuterons through a Ni single crystal. The setup is described, which contains permanent magnets with a transversal magnetic field to increase the deuteron polarization using Sona-method (zero transition). The measurements of tensor polarization were carried out with TiT target. The result is $${{P}_{{zz}}} = - 0.12 \pm 0.04$$ for a weak field at the target without channeling. The ultimate aim is to produce 14-MeV polarized neutrons which will be used jointly with the frozen-spin polarized deuteron target for measurement $$\Delta {{\sigma }_{T}}$$ and $$\Delta {{\sigma }_{L}}$$ asymmetries in the $$nd$$ ‑transmission experiment.
