L-alpha phase can be continuously swollen with pure water which is governed by an equation of state (i.e., osmotic pressure versus period) and thermally excited fluctuation amplitudes that can be well described ... amount of ZnO is much smaller than that of filler, ZnO scattering can be neglected. Owing to multiple scattering effects, however, SANS ...

instrument S18 is a perfect crystal neutron interferometer which can also be configured as a high resolution Bonse Hart camera. This instrument can be used for precise measurement of neutron scattering lengths

The sample chamber The sample can be placed either in sample chamber (opposite) under vacuum and at low temperature or in a furnace.

The detector The position sensitive neutron detector (PSD) is a set of 3He tubes. The assembly can be moved inside the detector tank to adjust the instrument resolution. When the photo was taken, not all

wavevector transfer values Qel as low as 0.03 Å -1 at 20 meV incident energy can be reached. The position of the two-dimensional detector can be adjusted to cover different small-angle ranges between 1° and 15° ... 300-1900 K furnace A ~2 m2-area position sensitive gas detector ( 3 He) whose distance from the sample can be varied between 2 and 6 m ...

without any radial integration or energy rebinning. The typical actions carried on the BRISP data can be found in the brisp_pix2sqw.prox , and are below listed: w1=rdrun(24420) Short measure of direct ... w_el=w9 (optional) : the evaluation of the elastic channel is made for each of the 160 x 128 pixels, and can be done either using the elastic ...

intensity and resolution: one can use a coarse monochromatization (5 to 15 %). The resolution goes as λ 3 , so it becomes excellent at long wavelength. For example IN15 which can use 24 Å neutrons (wavelength ... (wavelength twice the one of IN11) can reach resolution around 1 neV (240 kHz). In addition it has two options: a TOF mode of operation ...

standard focusing conditions the momentum resolution δ|Q| is about δ|Q| ≈ 0.02 Å-1. If needed, δ|Q| can be considerably enhanced by beam collimation with compromises in neutron flux. Sample environment ThALES ... polarized and analyzed with large focusing Heusler monochromators and analyzers. Polarization analysis can be done either with Helmholtz ...

ar data. With a maximum scattering angle of about 85° of the detector arm Q-values up to 2.1 Å -1 can be reached for complementary measurements probing small length scales. The flexibility of the instrument ... e the specific requirements for incident and outgoing resolutions. Specialised sample environment can be provided including a cryo-furnace ...

Optionally the beam can be polarised simultaneously (i.e. select only the neutrons which have spins all in the same direction). The monochromatic beam is shaped by a set of slits and can be shut-off by a ... films and lipid layers with surfactants, the structure and the interfaces between these and solutions can be studied.
