| Abstract: | Abstract: OffSpec is one of the seven new spectrometers operational from day one in the second Target Station (TS2) at the pulsed spallation neutron source ISIS. OffSpec is a time-of-flight, low-background reflectometer specialized in off-specular scattering. It is unique because in addition to conventional reflectivity techniques, it is capable of using the neutron spin-echo angle labelling technique. One of the many possibilities of using this technique is measuring structures on a surface with the length scale of 20nm–15μm. Up to now the calibration of this length scale was made on the prototype instrument in Delft by measuring magnetic line integrals. This showed that the pole shoe design, an essential part of the spin-echo encoding, was not perfect, resulting in a different effective magnetic encoding angle from the physical angle. Recent reflection measurements on gold gratings not only confirmed this but also resulted in a reliable calibration. [Copyright &y& Elsevier] |
