Virtual Infrastructure for Scientific Analysis (VISA) Workshop https://pan-training.eu/materials/virtual-infrastructure-for-scientific-analysis-visa-workshop We invite you to view our workshop – hosted jointly by ExPaNDS and PaNOSC! VISA provides remote data analysis services giving access to experimental data, analysis software, compute infrastructure and expert-user support (IT and Scientific). The online half-day Workshop is open to all external stakeholders (especially scientists and IT staff but not limited to). We aim to demonstrate to beamline scientists the possibilities offered by VISA for data analysis and gathering IT staff around the table to discuss about the development and further deployment of the platform. VISA has been developed at a critical time (during the COVID-19 crisis) to answer data analysis needs and allowing remote instrument control. It provides simplified access for scientists to data analysis tools, offers remote support to users from experts and allows them to remotely control their experiments with the assistance of on-site instrument scientists. VISA allows a user to use the Remote Desktop as if they were sitting in front a data treatment workstation at the host institute and embeds JupyterLab directly accessible from the same platform interface. Initially developed at the Institut Laue-Langevin (ILL) in Grenoble, France and further deployed in the context of PaNOSC, VISA enables the PaN research infrastructures (PaN RIs) to work together on further scientific collaborations to solve 21st century challenges. The first session of the workshop showcases the implementation of VISA at the PaN RIs through ExPaNDS and PaNOSC partner’ demos and illustrate its use for scientific users and others. The second session in the afternoon focuses on presentations on VISA development and deployment (on OpenStack and other infrastructures), paving the way for a roundtable discussion on the future of VISA: sustainability and future collaborations. Video recording (direct link to vimeo) will be available soon. VISA, expands, PaNOSC, remote data analysis services
Neutrons for Magnetic Nanostructures on Surfaces: Beyond the Specular Intensity Wars

Polarized Neutron Reflectometry (PNR) is a great method to study magnetism of surface near structures on the nm scale. It is especially useful for functional materials and fundamentals of nano magnetism. The applications of the technique and the related grazing incidence scattering include...

Neutrons for Magnetic Nanostructures on Surfaces: Beyond the Specular Intensity Wars https://pan-training.eu/materials/neutrons-for-magnetic-nanostructures-on-surfaces-beyond-the-specular-intensity-wars Polarized Neutron Reflectometry (PNR) is a great method to study magnetism of surface near structures on the nm scale. It is especially useful for functional materials and fundamentals of nano magnetism. The applications of the technique and the related grazing incidence scattering include multiferroic heterostructures, correlated electron systems, exchange bias, superconductors, magnetic nanoparticles and spin textures like skyrmions. Many of these systems have in common that the sample sizes are small, leading to intensity limited experiments.
