Performance of the neutron polarimeter NPOL3 for high resolution measurements
We describe the neutron polarimeter NPOL3 for the measurement of polarization transfer observables Dij with a typical high resolution of ∼300 keV at Tn ≃ 200 MeV. The NPOL3 system consists of three planes of neutron detectors. The first two planes for neutron polarization analysis are made of 20 sets of one-dimensional position-sensitive plastic scintillation counters with a size of 100 cm × 10...
متن کاملA `beam-selection' high-resolution X-ray diffractometer
A new diffractometer that can be described as a high-intensity low-background high-resolution diffractometer for analysing perfect, nearly perfect and highly imperfect materials on a routine basis is presented. The instrumentation is very simple and uncomplicated, yet the way in which it works is less obvious. The sample requires minimal sample alignment, the resolution can be adjusted to optim...
متن کاملA compact high-resolution X-ray powder diffractometer
A new powder diffractometer operating in transmission mode is described. It can work as a rapid very compact instrument or as a high-resolution instrument, and the sample preparation is simplified. The incident beam optics create pure Cu Kα1 radiation, giving rise to peak widths of ∼0.1° in 2θ in compact form with a sample-to-detector minimum radius of 55 mm, reducing to peak widths of <0.05° i...
متن کاملXtremeD – a new neutron diffractometer for high pressures and magnetic fields at ILL developed by Spain
Neutron diffraction has unique capabilities for scientific research under extreme conditions, mainly in two large areas: crystallography/geosciences and magnetism/solid-state physics. The growing interest in these fields is attested by the quantity and quality of publications, by the number of experiments proposed at the different neutron sources and by the new instrumentation projects under de...
متن کاملTexture Measurements Using the New Neutron Diffractometer HIPPO and their Analysis Using the Rietveld Method
In this paper we describe the capabilities for texture measurements of the new neutron time-offlight diffractometer HIPPO at the Los Alamos Neutron Science Center (LANSCE). The orientation distribution function (ODF) is extracted from multiple neutron time-of-flight histograms using the full-pattern analysis first described by Rietveld. Both, the well-established description of the ODF using sp...
