Recherche et optimisation – le SwissFEL en 2019

SwissFEL Matière et matériaux Recherche sur les matériaux Recherche avec la lumière synchrotron

La plus récente grande installation de recherche du PSI, le SwissFEL, est achevée. Elle a commencé à fonctionner normalement en janvier 2019. Henrik Lemke, responsable du groupe SwissFEL Bernina, tire un premier bilan.

La star à l’écran: une machine moléculaire

Communiqués de presse Biologie SwissFEL Grands instruments de recherche Recherche avec la lumière synchrotron

Des chercheurs de l’Institut Paul Scherrer PSI ont filmé une machine moléculaire en mouvement grâce à la Source de Lumière Suisse SLS, et ainsi révélé comment fonctionne la production d’énergie au niveau des cellules membranaires. Ils ont développé à cet effet une nouvelle méthode qui pourrait permettre des succès inédits dans l’analyse des processus cellulaires.

PSI School for Masterstudents 2019

PSI School for Master Degree Students - Introducing Photons, Neutrons and Muons for Condensed Matter Physics and Materials Science

From 17 – 21 June 2019 the Neutron and Muon Division (NUM) and the Photon Science Division (PSD) of PSI hosted 18 Master Degree students of physics, chemistry, materials and interdisciplinary science, as well as nuclear engineering to provide an introduction to the characterization of materials with large scale facilities like SINQ, SμS, SLS and SwissFEL. The course taught a basic understanding of how photons, neutrons and muons interact with matter, and how this knowledge can be used to solve specific problems in materials research.

Details of the program can be found at http://indico.psi.ch/event/PSImasterschool

Towards X-ray Transient Grating Spectroscopy at SwissFEL

The high brilliance of new X-ray sources such as X-ray Free Electron Laser opens the way to non-linear spectroscopies. These techniques can probe ultrafast matter dynamics that would otherwise be inaccessible. One of these techniques, Transient Grating, involves the creation of a transient excitation grating by crossing X-ray beams on the sample. Scientists at PSI have realized a demonstration of such crossing by using an innovative approach well suited for the hard X-ray regime.

First femtosecond protein pump-probe measurements at SwissFEL

A major milestone in the commissioning of SwissFEL has been reached: the first pump-probe experiments on proteins have been successfully carried out. Crystals of several retinal-binding proteins were delivered in a viscous jet system and a femtosecond laser was used to start the isomerization reaction. Microsecond to sub-picosecond snapshots were then collected, catching the retinal proteins shortly after isomerization of the chromophore.

L'UE accorde 14 millions à des chercheurs suisses

Communiqués de presse Recherche sur les matériaux Matière et matériaux Recherche avec des neutrons Grands instruments de recherche

Une prestigieuse bourse de l’Union européenne a été décernée à une équipe incluant trois chercheurs du Domaine des EPF. Les scientifiques ont reçu aujourd’hui le contrat signé de l’UE qui confirme ce financement exceptionnellement important de 14 millions d’euros. Ce montant va leur permettre d’étudier certains effets quantiques qui pourraient constituer l’épine dorsale de l’électronique du futur.

Bernina status first summer shutdown

The summer shutdown was used to install more missing hardware. With the new components the Bernina instrument will be already very close to the full design capabilities when the exciting time of user experiments will begin in 2019.
