The single crystal diffractometer HEiDi is designed for detailed studies on structural and magnetic properties of single crystals using hot unpolarised neutrons and Bragg’s Law:
2 dhkl sin (Θ) = λ
(typically 0.55 Å < l < 1.2 Å).
Because of the large variety of short wavelengths and resolutions, HEiDi is suitable for studies on a lot of crystalline compounds – many of them of potential interest for energy or data storage technologies – like:
