We evaluated the neutron-detection characteristics of a cryogenic neutron detector operating at 1.6 K, which comprises a liquid helium-3 as a neutron converter and an InSb semiconductor detector. The InSb semiconductor detector detected the protons created in the nuclear reaction $^{3}He + n rightarrow p + T$ in the liquid helium-3, where the density of that is ~600 times larger than that of the gaseous helium-3 at room temperature.
