摘要：

At one of the cold-neutron guides at the Dhruva reactor at Trombay, we are testing a modestly designed neutron spin-echo spectrometer, which would be suitable for the study of dynamics at an intermediate length of about 1 nm and a time up to 1 ns. We use a BeO-filtered quasi-monochromatic beam and a multi-stage soller-type design of the supermirror polarizer and analyser, which allows focussing of the neutron beam by a suitable choice of the angles between the various columns of the supermirrors. The spin-echo signal has been observed for the direct beam, and further calibration experiments are in progress.
