Abstract
The neutron measurement properties of Rh-SPNDs are greatly
affected by their geometric constructions, which needs to be
optimized while designing. This effect is reflected in the
sensitivities for gamma and neutron detection. However, the
influence on gamma sensitivity has not been fully analyzed before,
which is of the same importance as neutron sensitivity. Therefore,
it is necessary to quantitatively analyze the relationship between
detector sensitivity and geometric dimensions. The effect of Rh-SPND
structural and material parameters on neutron and gamma
sensitivities has been calculated and analyzed through numerical
simulations. The research results show that detector sensitivities
are strongly depending on the detector size and its emitter
shape. Moreover, the detector response to exogenous reactor gamma
can be eliminated by optimizing the detector collector size.
