🗞️ What if we could read inside a fragile lead scroll from the Viking era… without ever opening it? This lead scroll was so delicate that unrolling it would have risked irreversible damage. Since its discovery, its inside contents had remained inaccessible - until neutron tomography stepped in.

Neutrons totally reflect from material surfaces up to a critical angle that depends both on the neutron wavelenght and on the material Critical angles vary with wavelength and material, with nickel having the highest reflection angle. Supermirrors are multilayer structures designed to reflect neutrons at angles exceeding the critical angle. These devices consist of alternating layers of materials with varying neutron scattering lengths. The performance of these supermirrors depends on layer thickness,composition, and perfection.
At ILL, supermirrors are manufactured using magnetron sputtering to deposit materials with precise control of layer thickness on the nanometre scale. Polarising supermirrors use alternating magnetic material layers to preferentially reflect neutrons of one spin state while absorbing or transmitting the other. Substrate choice and geometry also play a crucial role in optimising performance.
