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: Der neue Kran kommt von oben
Die Synchrotron Lichtquelle Schweiz SLS bekommt einen zweiten Hallenkran. Aber wie schafft der es ins Gebäude? Da bleibt nur der Weg durch das Dach.
Magische Kraft mit grosser Wirkung
Mikroroboter, Materialien mit Formgedächtnis oder bessere Teilchenbeschleuniger werden möglich durch die Erforschung des Magnetismus am PSI.
Zuwachs bei den Datenwissenschaften
Am PSI wird ein weiterer Standort des Swiss Data Science Center entstehen. Der Ausbau soll den Datenwissenschaften in der Schweiz einen weiteren Schub verleihen.
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.

Mehr Magnete, weichere Kurven: das Upgrade der SLS
Die Synchrotron Lichtquelle Schweiz SLS soll in den kommenden Jahren ein Upgrade bekommen: Die SLS 2.0. Der Umbau wird möglich durch neueste Techniken und wird eine Grossforschungsanlage schaffen, die für weitere Jahrzehnte den Bedürfnissen der Forschenden gerecht wird.
3D imaging for planar samples with zooming
Researchers of the Paul Scherrer Institut have previously generated 3-D images of a commercially available computer chip. This was achieved using a high-resolution tomography method. Now they extended their imaging approach to a so-called laminography geometry to remove the requirement of preparing isolated samples, also enabling imaging at various magnification. For ptychographic X-ray laminography (PyXL) a new instrument was developed and built, and new data reconstruction algorithms were implemented to align the projections and reconstruct a 3D dataset. The new capabilities were demonstrated by imaging a 16 nm FinFET integrated circuit at 18.9 nm 3D resolution at the Swiss Light Source. The results are reported in the latest edition of the journal Nature Electronics. The imaging technique is not limited to integrated circuits, but can be used for high-resolution 3D imaging of flat extended samples. Thus the researchers start now to exploit other areas of science ranging from biology to magnetism.
