Orientation Effect in D + D Reaction Initiated by 20 keV Deuterons at Channeling in Textured Cvd-diamond Target

TL;DR

This study investigates how the orientation of a textured CVD-diamond target affects the enhancement of the D + D nuclear reaction initiated by 20 keV deuterons, using simulation and experimental comparison.

Contribution

It introduces a simulation-based analysis of orientation effects on reaction enhancement in textured diamond targets, aligning with experimental observations.

Findings

Flux peaking increases enhancement factor up to 2.2 times for parallel beam

Enhancement factor increases up to 1.2 times with 3 critical channeling angles

Qualitative agreement between simulation and experiment achieved

Abstract

Orientation effect of increasing the enhancement factor of DD reaction in CVD-Diamond was investigated by simulation. It is obtained that the flux peaking effect up to 2.2 times increases the relative enhancement factor for a parallel beam and up to 1.2 times for the deuteron beam with angular divergence equals 3 critical channeling angles. Qualitative agreement with the experiment was obtained.
