title = "Effect of hydrogen on NiTi multilayer neutron monochromator performance",
abstract = "NiTi multilayers with and without hydrogen added to the Ti layers have been prepared by dc-magnetron sputtering to investigate the effect of hydrogen on neutron monochromator performance. The addition of hydrogen further reduces the negative scattering length density of Ti, thereby increasing the contrast with the Ni. Increases in the first order peak reflectivity by factors of 2-3 have been observed in neutron reflectivity measurements. The improved performance is attributed to a larger neutron scattering length density contrast and to a sharpening of the interfaces.",
