Research and Development of the Polarized Deuteron Source for the Electrostatic Accelerator
The prototype of polarized deuteron source was made for the Van de Graaff accelerator of the Czech Technical University in Prague with aim to create full scale setup for producing polarized neutron beam for experiments on measurement \(\Delta {{\sigma }_{{\text{L}}}}\) and \(\Delta {{\sigma }_{{\text{T}}}}\), longitudinal and transversal spin asymmetries in transmission polarized neutron beam through frozen polarized deuteron target. It is based on Kaminsky’s experiment on channeling deuterons through a magnetized Ni single crystal foil of 1–2 μm. It is proposed to use the reaction T\({{(d,n)}^{4}}\)He with polarized deuterons of an energy 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 \({{P}_{{zz}}} = - 0.10 \pm 0.02\). This result indicates that deuterium atoms that have passed outside the channels also become polarized due to the capture of polarized electrons from the nickel crystal.
