Description
The energy dependence of the neutrons yield from d(d,n)3He reaction at deuterons energy 7÷12 KeV in the textured TiD2 target (the micro crystals are aligned mainly along <100> direction) was studied recently in [1] using pulsed plasma Hall accelerator with closed electron current (PHA). In Ref. [2] the authors investigated the neutron yield in the same reaction using textured CVD-Diamond and 30 KeV deuteron beam from HELIS accelerator with small angular and energy divergences. The authors of [1-2] suggested that the observed enhancement of neutron yield is connected both with the screening and channeling effects.
To clarify the role of channeling in enhancement of neutrons yield in d(d,n)3He reaction in TiD2 crystal target, we present here the results of computer simulations. The deuterons trajectories in a TiD2 crystal are simulated using the computer code Basic Channeling with Mathematica™ (BCM-1) [3], which allows calculate angular and spatial distribution of channeled particles in a thin crystals, see e.g. [4]. The simple model to calculate the reaction yield revealed the remarkable orientation effect directly connected with flux-peaking of deuterons in a crystal. The comparison with experimental data [1] is performed.
