In this work, the neutron emission characteristics of a thick titanium deuteride (TiD_x) target bombarded by deuteron beams with energies up to 10 MeV are investigated, with emphasis on the energy range relevant to high-intensity linear accelerators. An improved multi-layer thin-target summation method suitable for thick-target conditions is developed and implemented to systematically evaluate neutron yield, angular distributions, and energy spectra. The results indicate that the neutron yield increases rapidly with deuteron energy below 2 MeV and gradually approaches a slower growth regime at higher energies. Under a 2 MeV deuteron beam and a TiD atomic ratio of 2.0, the neutron yield reaches nearly 10¹¹ n/s/mA. The calculated angular distributions are generally consistent with available differential cross-section data. The neutron energy spectra exhibit pronounced angular dependence, with significant broadening at forward angles and quasi-monoenergetic emission predominantly at backward angles above 90°. Monte Carlo simulations using Geant4, PHITS, and FLUKA were also performed for comparison.

By expressing this diquark-diquark-antiquark configuration in Jacobi coordinates, the three–body dynamics are significantly simplified within the HCQM framework.
