摘要：

The detection efficiency of a solid state ultracold neutron (UCN) detector operating at liquid helium temperature was improved by coating the neutron converter with a 6Li/Ti multilayer and a protective Ti layer. The decreased neutron reflectivity of the multilayers permits the penetration of long wavelength neutrons into the UCN detector.
