A compact and cost-effective hard X-ray free-electron laser driven by a high-brightness and low-energy electron beam

Lukas Stingelin, Majed Chergui, Paul Beaud, Thomas Schietinger, Christopher Alexander Arrell, Thomas Schmidt, Leonid Rivkin, Christoph Peter Hauri, Giulia Fulvia Mancini, Rasmus Ischebeck, Eugenio Ferrari, Camila Bacellar Cases Da Silveira, Mike Seidel, Paolo Craievich, Sven Reiche

We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very stable, compact and cost-effective X-ray FEL facility driven by a lo ...

The SwissFEL soft X-ray free-electron laser beamline: Athos

Thomas Schietinger, Christopher Alexander Arrell, Thomas Schmidt, Rasmus Ischebeck, Eugenio Ferrari, Christoph Bostedt, Paolo Craievich, Sven Reiche

The SwissFEL soft X-ray free-electron laser (FEL) beamline Athos will be ready for user operation in 2021. Its design includes a novel layout of alternating magnetic chicanes and short undulator segments. Together with the APPLE X architecture of undulator ...

Two primes priming: Does feature integration occur before response activation?

Michael Herzog, Frank Scharnowski, Thomas Schmidt, Julianne Grainger

Responses to a target can be sped up or slowed down by a congruent or incongruent prime, respectively. Even though presentations are rapid, the prime and the target are thought to activate motor responses in strict sequence, with prime activation preceding ...

X-Treme beamline at SLS: X-ray magnetic circular and linear dichroism at high field and low temperature

Harald Brune, Stefano Rusponi, Thomas Schmidt, Jan Gui-Hyon Dreiser

X-Treme is a soft X-ray beamline recently built in the Swiss Light Source at the Paul Scherrer Institut in collaboration with Ecole Polytechnique Federale de Lausanne. The beamline is dedicated to polarization-dependent X-ray absorption spectroscopy at hig ...

A thermodynamic and experimental study of the conditions of thaumasite formation

Karen Scrivener, Thomas Schmidt, Barbara Lothenbach

The formation of thaumasite was investigated with the progressive equilibrium approach (PEA). This approach experimentally simulates the conditions of various levels of sulfate addition in hardened cement pastes. The influence of limestone, time, C(3)A con ...

Sulfate attack and the role of internal carbonate on the formation of thaumasite

Thomas Schmidt

The sulfate attack is known to influence the durability of concrete. In general, significant damage due to sulfate interaction results in the structural breakdown of the concrete structure. However, the precipitation of thaumasite due to sulfate concentrat ...
