Abstract

Abstract : The article describes recent upgrades of the polarized neutron reflectometer D17 at the Institut Laue–Langevin, Grenoble, France, and presents recent examples of scientific studies enabled with the new options. Abstract : The vertical sample‐plane reflectometer D17 at the Institut Laue–Langevin in Grenoble, France, has undergone several major upgrades since its commissioning, which are summarized in this article. The three major improvements are (i) a new focusing guide, increasing the usable flux on the sample by a factor of 2.5; (ii) a new beam polarizer and new spin flippers, allowing for the use of polarized neutrons in time‐of‐flight mode; and (iii) a new detector with a particularly uniform response under homogeneous exposure, improved stability and state‐of‐the‐art detector electronics. The combination of these factors has paved the road to new possibilities in fast kinetic measurements, magnetism and off‐specular scattering. Examples and scientific references for the new capabilities are presented.
