CAMEA - A Novel Neutron SpectrometerF. Groitl et al., Review of Scientific Instruments 87, 035109 (2016). Following extensive optimization and prototyping the CAMEA project, a joint venture between LNS (PSI) and the Laboratory for Quantum Magnetism (EPFL), enters its next stage. The design is finalized, procurement has started and assembly at the current cold triple-axis spectrometer RITA-2 will start in 2017. The innovative multiplexing design employs a series of upward-scattering arcs of analyzer crystals combined with an array of position sensitive 3He detectors. The chosen configuration allows for a continuous final energy coverage from 3.2 to 5.1 meV and a quasi-continuous angular coverage of 60° resulting in tremendous gains in data collection rates. In a single data acquisition several constant-energy lines (~3000 data points) in the horizontal scattering plane are recorded and a simple sample rotation scan generates several constant-energy maps. The instrument is optimized for in-plane scattering and particularly suited for parametric studies under extreme conditions. The project is financed by the R’Equip program of the Swiss National Science Foundation, EPF Lausanne and PSI.

Björn Wehinger's work on cristobalite on the cover of JPCMThe publication "Lattice dynamics of α-cristobalite and the Boson peak in silica glass" by Björn Wehinger, Alexeï Bosak, Keith Refson, Alessandro Mirone, Aleksandr Chumakov and Michael Krisch, J. Phys.: Condens. Matter 27, 305401 (2015), marks a decisive step in the solution of the longstanding problem understanding the origin of the Boson peak in silica glass. The investigation by means of diffuse and inelastic x-ray scattering and lattice dynamics calculations from first principles allow for a direct comparison of the atomic motion in crystalline silica polymorphs and silica glass. The article was selected to illustrate the cover page of Journal of Physics: Condensed Matter, Vol. 27, Nr. 30. The animation shows the intensity distribution of thermal diffuse scattering in 3D reciprocal space.

Frontier Experiments with NeutronsThe annual meeting of the Swiss Physical Society (SPS) will take place June 30 - July 2, 2014 at the University of Fribourg, Switzerland. At this meeting the Swiss Neutron Scattering Society (SGN/SSDN) is organising a focussed session on 'Frontier Experiments with Neutrons'. It will cover both scientific highlights and frontiers in instrumentation and source development. We particularly encourage abstract submissions from young scientists who use neutron scattering as an experimental tool for their research, whatever the topic. In this way, we will be able to present the full range of interests of the Swiss neutron scattering community. The SGN/SSDN will also award its thesis medal during the session. Deadline for abstract submission is March 15, 2014. For further questions please contact the SGN organisers Tom Fennell and Martin Mansson.

New CAMEA SpectrometerAs joint venture with the Laboratory for Quantum Magnetism LQM of Prof. H.M. Ronnow at EPF Lausanne, construction of the new spectrometer CAMEA (Continuous Angle Multiple Energy Analyzer) has started, which will be installed as option at the current RITA-2 instrument at SINQ. This new spectrometer will be particularly suited for parametric studies under extreme conditions requiring restrictive sample environments such as high magnetic field magnets or pressure cells, and for experiments on small samples of novel materials. The novelty of the CAMEA design is that it employs a series of several upward-scattering analyzer arcs. This design allows each analyzer to collect neutrons over different energy ranges and a large solid angle that are measured simultaneously by position sensitive detectors. In a single data acquisition an entire constant-energy line in the horizontal scattering plane is recorded for a quasi-continuous angular coverage with tremendous gains in data collection rates. The project is financed by the R’Equip program of the Swiss National Science Foundation, EPF Lausanne and PSI.

2013 ESS Science Symposium: Neutrons for Future Energy StrategyMay 27-29, 2013, at the Paul Scherrer Institute. Finite fossil fuel reserves and growing environmental concerns have lead to an increase of interest in so-called renewable energy sources such as wind, solar or water energy. Consequently, the conversion and storage of energy and the supply of synthetic fuels will become more and more important in the near future. This symposium will bring together experts from the fields energy research and scientists from the neutron scattering community. In the context of this symposium energy research will refer to synthetic fuels, solar cells, fuel cells and batteries and materials for turbines (wind and/or water). Emphasis will be put on sample environment, in particular for in-situ and operando experiments; on correlations between structure and transport processes, on interactions of materials with their ambient environment; and on synergies with synchrotron radiation and muon spin spectroscopy. The symposium will cover all topics from diffraction to spectroscopy and imaging.
