Scientific Highlights and News
The upgrade of the SLS to a diffraction-limited storage ring (DLSR) will benefit in particular those experimental techniques that exploit coherence and/or beam collimation and tight focussing. The increased coherent fraction, of the order of several percent in the hard x-ray regime, will greatly enhance phase-contrast tomography and lensless-imaging techniques such as ptychography; the ability to focus down to micron dimensions while maintaining excellent collimation will allow the investigation of proteins that only form micro- and nanocrystals, most notably membrane proteins and G-coupled protein receptors (GCPRs). The below articles contain recent news and examples, all performed at the SLS, which have been selected as representatives of some of the clearest scientific drivers for the upgrade of the SLS; such experiments at SLS 2.0 will be able to be performed either much more rapidly, or with significantly greater spatial resolution.
SLS: le nouveau pont roulant vient du ciel
La Source de Lumière Suisse SLS se voit dotée d’un deuxième pont roulant. Mais comment entre-t-il dans le bâtiment? Le seul moyen est de passer par le toit.
Une force magique qui fait grand effet
Des microrobots ou de meilleurs accélérateurs de particules deviennent possibles par la recherche sur le magnétisme au PSI.
Un nouveau site pour les sciences des données
Un nouveau site du Swiss Data Science Center va voir le jour au PSI. Cette expansion devrait donner un nouvel élan à la science des données en Suisse.
SLS 2.0 approved - TOMCAT 2.0 cleared for takeoff!
In December 2020 the Swiss parliament approved the Swiss Dispatch on Promotion of Education, Research and Innovation (ERI) for 2021 to 2024 which includes funding for the planned SLS 2.0 upgrade. The new machine will lead to significantly increased brightness, thus providing a firm basis for keeping the SLS and its beamlines state-of-the-art for the decades to come. The TOMCAT crew is very excited that the TOMCAT 2.0 plans (deployment of the S- and I-TOMCAT branches, see SLS 2.0 CDR, p. 353ff) have been included in the Phase-I beamline upgrade portfolio. These beamlines will receive first light right after the commissioning of the SLS 2.0 machine around mid 2025. A first milestone towards this goal has just been achieved, with the successful installation of the S-TOMCAT optics hutch during W1 of 2021. The TOMCAT scientific and technical staff would like to thank Mr. Nolte and his Innospec crew for delivering perfectly on schedule.
Le PSI équipe la Source de Lumière Suisse SLS pour l’avenir
Feu vert pour la SLS 2.0: l’upgrade de la Source de Lumière Suisse SLS peut avoir lieu. Le financement est assuré dans le cadre du message FRI 2021-2024 approuvé à la mi-décembre.
«Nous préparons la SLS à l’avenir»
La Source de Lumière Suisse SLS doit faire l’objet d’une mise à jour afin qu’elle puisse aussi permettre une recherche d’excellence au cours des prochaine décennies. Dans cette interview, Hans Braun, chef du projet SLS 2.0, explique en quoi consiste cet upgrade.
SLS 2.0: l’upgrade de la Source de Lumière Suisse SLS
Au cours des prochaines années, la Source de Lumière Suisse SLS fera l’objet d’un upgrade: la SLS 2.0. Cette transformation rendue possible par de la technologie dernier cri donnera une grande installation de recherche à la hauteur des besoins des chercheurs pour les prochaines décennies.
Time-resolved copper speciation during selective catalytic reduction of NO on Cu-SSZ-13
Through the combination of time-resolved X-ray absorption spectroscopy and transient experimentation, we were able to capture an ammonia inhibition effect on the rate-limiting copper re-oxidation at low temperature.
Nanostructure surveys of macroscopic specimens by small-angle scattering tensor tomography
The mechanical properties of many materials are based on the macroscopic arrangement and orientation of their nanostructure. This nanostructure can be ordered over a range of length scales. In biology, the principle of hierarchical ordering is often used to maximize functionality, such as strength and robustness of the material, while minimizing weight and energy cost.
