On feasibility of the experiments with a polarized deuteron beam and a polarized target at Charles University in relation with polarized fusion

Abstract

There is an interest in the problem of polarized fusion with the neutron-free d3He reaction. Up to now, the experimental data on the cross sections of two dd reactions, which produce neutrons at once or through secondary dt reaction, are absent for polarized deuterons. There is a relatively cheap way to carry out the experiments with polarized deuterons at the Charles University in Prague. A polarized deuteron beam with energy from 100 keV up to approximately 1 MeV may be produced on the Van de Graaff accelerator by the channeling of a deuteron beam through magnetized Ni single crystal foil, according M. Kaminsky [Phys. Rev. Lett. 23, 819 (1969)]. This method permits to produce a polarized deuteron beam of an energy ⩽1 MeV with a current of ∼1 nA, vector polarization P3 up to 2/3 and tensor polarization P33=0. It will be necessary to modify the existing polarized target at Charles University for work with a low energy deuteron beam [N. S. Borisov et al., Nucl. Instr. & Meth. A 345, 421 (1994)].
