The impact of the nonionic surfactant, dodecyl triethyleneglycol ether (C(12)E(3)) on the solution microstructure of the dialkyl chain cationic surfactant, dihexadecyl dimethyl ammonium bromide, (DHDAB) has been investigated. The variation in solutio

A small-angle neutron scattering spectrometer that uses a refractive focusing optic can reach smaller values of the scattering vector, and with higher resolution, than that using pinhole collimation. The analytic expression for the resolution is inde

We propose two neutron radiographic techniques that make use of the converging beam from a tapered monolithic lens. The first is a focusing technique that enables one to obtain an image of a given cross section within an object. The second technique

The transmission and the number of reflections of successful neutron trajectories through a straight cylindrical tube with a coaxial aperture at its entrance have been calculated, assuming that a beam with a conical angular divergence is incident alo

The average number of reflections for radiation transmitted by a straight cylindrical channel can be determined analytically for an input beam for which the divergence has polar symmetry. For the case of an incident beam with a divergence of Cartesia

Materials-analysis measurements that employ neutron-absorption techniques may benefit from cold neutrons that may be focused using a lens consisting of polycapillary fibers. An expression is derived for the intensity gain and the size of the beam alo

Small-angle neutron scattering instruments use large source and sample areas with long flight paths to obtain the necessary resolution. Increased count rates may be obtained using collimators that converge to a point on the detector. Further increase

Capillary-fiber optics have been shown to be a useful technique for guiding and focusing both X-rays and neutrons by means of multiple reflection in hollow glass tubes and the principles of X-ray and neutron lenses have been demonstrated. An optimum

Approximate analytic expressions for determining the transmission of neutron benders which take into account reflectivity losses using the mean number of reflections agree well with computer simulation results which track the neutron trajectories dir
