LIN: Laboratory for Neutron and Muon Instrumentation
Through a unique mix of technical and scientific staff the Laboratory for Neutron and Muon Instrumentation (LIN) is central to the operation and development of scientific instrumentation and methods for the SINQ and UCN neutron sources as well as the SμS muon source at the Paul Scherrer Institut (PSI). These efforts enable both PSI researchers as well as the international scientific user community to carry out state-of-the-art experiments that employ neutron and muon particle beams to solve topical scientific issues in fields ranging from particle physics to solid state physics to materials science.

The Laboratory for Neutron and Muon Instruments visits FRM II neutron research facility
Recently, the staff of the PSI’s Laboratory for Neutron and Muon Instrumentation (LIN) visited our colleagues at MLZ to learn more about the FRM II reactor and its instrumentation, as well as to discuss current and future joint projects. LIN staff was greeted with Bavarian hospitality in the form of “Weisswurst Frühstück” and then enjoyed a full tour of the facility and many fruitful discussions.
Kinderuniversität Zürich visits PSI
On November 5, 2022, the Laboratory for Neutron and Muon Instrumentation in collaboration with the Correlated Quantum Matter group at the University of Zurich carried out the workshop “Wellenspiele” (German for “Playing with Waves”) for the Kinderuniversität Zürich (“Children’s University Zurich”) for the first time.
Artur Glavic received the first Instrumentation Price Neutron Research
Artur Glavic received the first Instrumentation Price Neutron Research “for his significant contributions to the development and construction of novel neutron reflectometers”.
Scientific Highlights
Single-domain stripe order in a high-temperature superconductor
The coupling of spin, charge and lattice degrees of freedom results in the emergence of novel states of matter across many classes of strongly correlated electron materials. A model example is unconventional superconductivity, which is widely believed to arise from the coupling of electrons via spin excitations. In cuprate high-temperature superconductors, the interplay of charge and spin degrees of freedom is also reflected in a zoo of charge and spin- density wave orders that are intertwined with superconductivity ...
Clarifying the fate of collective metallic quantum states
Many complex metals exhibit collective states in which electrons appear to collaborate to generate novel and frequently functional behavior. These states develop when metals are cooled down to remove the effects of thermal fluctuations, enabling collective states in which electrons move coherently through the material. These collective electronic states are of tremendous importance because they are the foundation for many quantum states of interest such as unconventional superconductivity, frustrated magnetism, hidden order, as well as topologically non-trivial and electronic-nematic states.
Unveiling Unequivocal Charge Stripe Order in a Prototypical Cuprate Superconductor
In the cuprates, high-temperature superconductivity, spin-density-wave order, and charge-density-wave (CDW) order are intertwined, and symmetry determination is challenging due to domain formation. We investigated the CDW in the prototypical cuprate La1.88Sr0.12CuO4 via x-ray diffraction employing uniaxial pressure as a domain-selective stimulus to establish the unidirectional nature of the CDW unambiguously.
