An attempt is made to develop a polarized deuteron source suited for the Van de Graaff accelerator of Czech Technical Universit in Prague. We base 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 the Sona method (zero transition). The measurements of tensor polarization were carried out with a TiT target. The result is Pzz = -0.12±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 of ΔσT and ΔσL asymmetries in the nd-transmission experiment.
