Device for measuring of the polarized neutron reflectivity using two polarized neutron super-mirrors

摘要

The present invention relates to a polarized neutron reflectometry apparatus using the two polarized neutron second mirror, neutron induction tube that guides the neutrons from the neutron source; A monochromator Monochromator neutrons emitted from the neutron induced tube; Is in the single color group from the neutron beam monochromator comprising the spin-up and spin-down neutrons having a specific wavelength, using a second polarized neutron second mirror for reflecting the first polarized neutrons and a second mirror that reflects the spin-up neutron spin down neutrons , a selector for determining a spin-spin form which is incident on the sample; Is selected from the neutron spin selector reduces the line width of a spin-out slit form to be incident on the sample; Analyzer using the second mirror to reflect or transmit according to spin form a neutron beam which is reflected from the sample; And the sample analyzer detects the neutron and the neutron transmitted through the transmission or reflection, and by measuring the reflectance of the detector; Provides a polarized neutron reflectometry apparatus comprising a. ; According to the present invention having a configuration as Thus, the structure of the polarized neutron reflectivity device becomes simple, the operation is simplified so that the effect is.
