Morphology of buried interfaces in ion-assisted magnetron sputter deposited 11B4C-containing Ni/Ti multilayer neutron optics investigated by grazing incidence small angle scattering
Sjoerd Broekhuijsen, Naureen Ghafoor, Matthias Schwartzkopf +3
Multilayer neutron optics require precise control of interface morphology for optimal performance. In this work, we investigate the effects of different growth conditions on the in…

Chemically homogeneous boron carbide 10B/11B isotope modulated neutron interference mirrors
J. Birch, S. Stendah, S. Dorri +3
We introduce a novel type of neutron interference mirrors based on a chemically homogeneous BxC (x>4) matrix with internal high precision 10B/11B isotope modulation. Simulations pr…

Material design optimization for large-m 11B4C-based Ni/Ti supermirror neutron optics
Sjoerd Stendahl, Naureen Ghafoor, Anton Zubayer +4
State-of-the-art Ni/Ti supermirror neutron optics have limited reflected intensity and a restricted neutron energy range due to the interface width. Incorporating low-neutron-absor…
