contribution to the surface composition (selected deuterated component in a multi-component system) can be measured at low Q in air contrast matched water with an uncertainty of 2% in as little as 1 min ... little as 1 sec. Structural measurements over the whole Q-range (0.005-0.4 A -1 ) in a D2O subphase can be measured in as little as 2 min. ...

High-resolution neutron imaging can uncover the workings of an electrolytic cell designed to turn the greenhouse gas carbon dioxide into useful chemicals. Experimental setup: Cell fixture and neutron ... neutron beam. Two heating cartridges inserted in the endplates (two holes going in from the front) can heat up the cell. Mitigating uncontrolled ...

methodological approach developed has been designed for this specific project, it is expected that it can be applied to a wide range of biological macromolecular complexes and provide structural information

symmetry-imposed trigonal field contribution; by directly probing the electronic states using INS one can characterise the effect of imidazole ligation to the metal. The observed Q-dependence is consistent

compared with the previous instrument. Detector scans are no longer required, since most experiments can now be carried out in a single detector position, resulting in dynamic q ranges of 0.02 - 1 Å -1 with ... detector positioned off the direct beam (SANS-WANS setup). The q-max remains unchanged at 2.5 Å -1 and can be reached by collecting data at ...

detector can be changed between 10’ and ˝open˝. The sample table can support the mounting of high-field cryomagnets (up to 12T and 15T, respectively in the polarised and unpolarised modes). IN22 can be operated ... or polarised mode. Vertical guide fields are permanently installed. The incident/final polarisation can be continuously selected in the ...

i = 2.66 Å -1 and 4.1 Å -1 are 0.82(3) meV and 3.05 (15) meV, respectively. Polarisation analysis can be performed in combination with the standard ILL 2.5 T and 6 T vertical-field and 4 T horizontal-field ...
