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

IR spectromicroscopy and imaging with six decades of dynamic range https://pan-training.eu/materials/ir-spectromicroscopy-and-imaging-with-six-decades-of-dynamic-range Speaker: Dr Ferenc Borondics, SMIS Beamline Manager, SOLEIL, France Infrared spectroscopy has been in scientists’ toolbox for more than a century to obtain information about vibrational properties and low energy electrodynamics of materials. The beginning of the 80s brought the first commercial infrared microscopes to look into fine details. Far-field infrared spectromicroscopy had been pushed to its limits in the 90s at synchrotron facilities by exploiting the unrivaled quality of synchrotron radiation, i.e., low angular divergence and extremely high bandwidth. Synchrotron infrared spectromicroscopy beamlines provide diffraction-limited spatial resolution covering the whole IR range and enable experiments impossible otherwise. Later, the implementation of two-dimensional IR detectors allowed hyperspectral imaging of large samples with high spatial resolution. The turn of the century brought the advent of near-field IR techniques breaking through the diffraction limit. Combining high-brightness IR sources with atomic force microscopes to detect photothermal expansion or near-field scattering allows measurements hundreds of times below the diffraction limit reaching as high as ten-nanometer spatial resolution. Optically sampled photothermal spectromicroscopy has recently become available to bridge the resolution gap between the nanometer and micrometer range. We combine these techniques at the SMIS beamline to enable six orders of magnitude spatial dynamic range in infrared spectromicroscopy and support scientific discovery by exploiting the synchrotron source through commercial and custom instrumentation. In this talk, I will highlight discoveries made by SMIS staff and users enabled by the beamline’s capability and comment on the benefits of emerging, alternative sources. infrared spectromicroscopy, imaging PaN Community beamline users scientists
