Description
The polarised neutron reflectometer Amor at PSI was equipped in 2020 with a Selene optics, replacing the old curved straight guide. This exchange took 3 months. It took an other 3 years to complete the secondary instrument (electronics, drives, detector, control software) and we started user operation in December 2023 - just before the accelerator maintenance shut-down.
We will present the technical implementation of the Selene optics, the polariser and the detector; discuss the performance of the instrument and present selected first experiments:
- In-situ battery (dis-)charging:
Lithium distribution in and swelling of germanium isotope multilayer
electrodes, observed over several charging cycles. - Investigation of catalysts for photo-induced hydrolysis:
Influence of a $\mathrm{NiO}$ protective layer on the
degradation of the catalyst
$\mathrm{CaTaO_2N}$. - Magnetic properties of high-entropy materials:
Influence of cooling and field history on the magnetic properties of
$\mathrm{Nd_5FeMnCoCrNiO_{15}}$.
