The polarized deuteron source for Van de Graaff accelerator

Abstract

An attempt is made to develop a polarized deuteron source suited for the Van de Graaff accelerator of Czech Technical University 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 P zz = −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 ∆σ T and ∆σ L asymmetries in the nd-transmission experiment.
