CUBIC NEUTRONS

Neutrons for rafts, rafts for neutrons.

The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment. We focus here on the possibility to apply neutron scattering to the study of...

The “higgs” from Anti-neutrons and Neutrons

The new anti-neutron, first proposed in 2011 [16], and ordinary neutrons, are both without electric charge, and are therefore rather difficult to accelerate and/or impact together in a high energy collider sufficient to cause annihilation, and thus create a 100% energy “Higgs” styled Boson, such Bosons arguably representing all of the mass in the universe. This very high energy impact combinati...

SUSANS With Polarized Neutrons

Super Ultra-Small Angle Neutron Scattering (SUSANS) studies over wave vector transfers of 10(-4) nm(-1) to 10(-3) nm(-1) afford information on micrometer-size agglomerates in samples. Using a right-angled magnetic air prism, we have achieved a separation of ≈10 arcsec between ≈2 arcsec wide up- and down-spin peaks of 0.54 nm neutrons. The SUSANS instrument has thus been equipped with the polari...

Imaging with Polarized Neutrons

Neutrons have zero net electrical charge and can thus penetrate deeply into matter, but their intrinsic magnetic moment makes them highly sensitive to magnetic fields. These properties have been combined with radiographic (2D) and tomographic (3D) imaging methods to provide a unique technique to probe macroscopic magnetic phenomena both within and around bulk matter. Based on the spin-rotation ...
