LIN builds pressure vessels for joint detector project with FRM-II in Munich
Highly efficient two-dimensional detectors are essential for the performance of modern neutron diffractometers. The NUM Division of PSI and the Technical University Munich TUM jointly develop two identical new 3He gas detectors, one for the diffractometer DMC at SINQ and the other for operation at FRM-II in Munich.
PSI participates in ECNS in St Petersburg
The European Conference on Neutron Scattering (ECNS) with its recent 2019 edition in St. Petersburg is a spree of lectures, poster sessions, and expert talks on the current trends and future possibilities in neutron science. PSI with its neutron source SINQ was represented by members of the two NUM laboratories LNS and LIN. In addition, PSI was silver sponsor of ECNS 2019 and is also a member of the LENS consortium (League of Advanced European Neutron Sources).
Soft biomimetic nanoconfinement promotes amorphous water over ice
Water is a ubiquitous liquid with unique physicochemical properties, whose nature has shaped our planet and life as we know it. Water in restricted geometries has different properties than in bulk. Confinement can prevent low-temperature crystalliza- tion of the molecules into a hexagonal structure and thus create a state of amorphous water. To understand the survival of life at subzero temperatures, it is essential to elucidate this behaviour in the presence of nanoconfining lipidic membranes.
Tomonaga-Luttinger Liquid Spin Dynamics in the Quasi-One-Dimensional Ising-Like Antiferromagnet BaCo2V2O8
Combining inelastic neutron scattering and numerical simulations, we study the quasi-one-dimensional Ising anisotropic quantum antiferromagnet BaCo2V2O8 in a longitudinal magnetic field. This material shows a quantum phase transition from a Néel ordered phase at zero field to a longitudinal incommensurate spin density wave at a critical magnetic field of 3.8 T.
