Description
HEiDi is a versatile single crystal diffractometer using unpolarized thermal and hot neutrons to provide users worldwide with high quality structure data. The applications range from studies on various magnetic compounds [Maity2021, Dutta2023, Zobkalo2023] and new battery materials [Redhammer2021] to complex framework structures [Lotti2023].
Heidi’s high neutron flux allows both studies up to a very high Q range and with strong absorbing sample environments like high pressure cells. The later was elaborated within two adjacent BMBF projects aiming to offer high pressure studies up to 10 GPa [Eich2021]. Currently, we are finalizing a small area detector (PSD) prototype to enhance HEiDi's general efficiency - faster and more comprehensive data collection - and to take a first step towards large Q studies for unpolarized neutron PDF analysis to serve the growing need on this kind of research.
