The prototype of a polarized deuteron source was made for the Van de Graaff accelerator of the Czech Technical University in Prague with the aim of creating a full-scale setup for producing a polarized neutron beam for experiments on measuring Δσ&sub(L) and Δσ&sub(T) , longitudinal and transverse spin asymmetries in transmission of a polarized neutron beam through a frozen polarized deuteron target. The method is based on Kaminsky’s experiment on channeling deuterons through a magnetized single-crystal Ni foil 1−2 μm thick. It is proposed to use the reaction T(d, n)*4He with polarized deuterons of an energy of 150−200 keV. For a nonchanneled beam (the goniometer in a random position), the tensor polarization measurements were carried out with a TiT target. Our result is P&sub(zz) = −0.10 ± 0.02. This result indicates that the deuterium atoms that have passed outside the channels also become polarized due to the capture of polarized electrons from the nickel crystal.
