tubes, totalling 2 m² of detection area. It has been relocated on the new H15 guide, benefiting from an improved collimation system and neutron flux. An increased brilliance by a factor 2-3 is achieved,

The phase diagram of NaPA in the presence of Ca 2 , dissolved in 0.01 M NaCl solution, is presented in figure 1. The subtle interplay of NaPA, NaCl with Ca 2 gives access to well defined and extremely small ... diagram of NaPA in the presence of Ca in an acqueous 0.01M NaCl solution.The grey region marks the 2 phase region, i.e. precipitation of ...

of a quantum spin liquid state with a spinon Fermi surface in YbMgGaO 4 , which has a perfect spin-1/2 triangular lattice as in the original proposal of quantum spin liquids by P.W. Anderson ( Mater. Res

observed. The spin resonance is only observed for temperatures below Tc, and has an energy ∆E = 0.43(2) meV.

Its low Δq/q resolution provided by a Δλ/λ = 0.01 combined to 1D slit collimation or 2D pinhole collimation provides a flexible beam geometry adapted to various sample shapes and sizes and ... the commissioning during the first reator cycle. At the core of the project was the new large, curved 2D MWPC He detector developped at ...

area of 256 x 256 mm 2 , a resolution (pixel size) of 2 x 2 mm 2 and a max. counting rate 100 kHz (less than 1% dead time). The replacement detector MILAND is larger (320 x 320 mm 2 ) and offers both a ... A rocking curve from a membrane multilayer recorded with the 256 x 256 mm2 detector.

and to evaluate the selectivity of the membrane permeation. Particularly, the effect of D 2 O, ethanol and D 2 O–ethanol vapours on graphene oxide (GO) thin films (≈25 nm) was studied. The interlayer spacing ... vapour exposure duration. The significant difference in neutron scattering length density between D 2 O and ethanol allows distinguishing ...

Long-range antiferromagnetic order in epitaxial Mn2GaC thin films The nature of the magnetic structure in magnetic so-called MAX phases is a topic of some controversy. Here we present unpolarized neut ... and momentum transfer between Q = 0.0 and 1.1 A-1 on epitaxial thin films of the MAX phase material Mn2GaC. This inherently layered material ...
