Assembling Ni-Fe Layered Double Hydroxide 2D Thin Films for Oxygen Evolution Electrodes

Hubert Girault, Andreas Stephan Lesch, Victor Costa Bassetto

Continuous hydrothermal flow synthesis (CHFS) of Ni-Fe layered double hydroxide (LDH) leads to waterborne dispersions of 2D nanoplatelets in the range of 10-50 nm in lateral size. Conversion of the as-synthesized LDH nanoplatelet dispersion into inkjet pri ...

Noninvasive LHC transverse beam size measurement using inelastic beam-gas interactions

Olivier Schneider, Zhirui Xu, Aurelio Bay, Guido Haefeli, Tatsuya Nakada, Frédéric Blanc, Plamen Hristov Hopchev, Mark Tobin, Olivier Göran Girard, Axel Kuonen, Sebastiana Gianì, Louise Helene Soegaard Jensen

The beam-gas vertex (BGV) detector is an innovative instrument measuring noninvasively the transverse beam size in the Large Hadron Collider (LHC) using reconstructed tracks from beam-gas interactions. The BGV detector was installed in 2016 as part of the ...

A teaching showcase unveils the links between special relativity and the birth of quantum physics

Giorgio Margaritondo

Quantum effects scale up with the frequency of electromagnetic waves. Therefore, modern synchrotron sources of high-frequency x-rays-that can be visited by students either personally or online-offer an opportunity for a captivating introduction to basic qu ...

Experimental station Bernina at SwissFEL: condensed matter physics on femtosecond time scales investigated by X-ray diffraction and spectroscopic methods

Christoph Peter Hauri, Giulia Fulvia Mancini, Christopher Alexander Arrell, Jochen Rittmann

The Bernina instrument at the SwissFEL Aramis hard X-ray free-electron laser is designed for studying ultrafast phenomena in condensed matter and material science. Ultrashort pulses from an optical laser system covering a large wavelength range can be used ...

Luminosity scans for beam diagnostics

Tatiana Pieloni

A new type of fast luminosity separation scans ("emittance scans") was introduced at the CERN Large Hadron Collider (LHC) in 2015. The scans were performed systematically in every fill with full-intensity beams in physics production conditions at the inter ...

The relativistic foundations of synchrotron radiation

Giorgio Margaritondo

Special relativity (SR) determines the properties of synchrotron radiation, but the corresponding mechanisms are frequently misunderstood. Time dilation is often invoked among the causes, whereas its role would violate the principles of SR. Here it is show ...

R&D around a photoneutralizer-based NBI system (Siphore) in view of a DEMO Tokamak steady state fusion reactor

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

Since the signature of the ITER treaty in 2006, a new research programme targeting the emergence of a new generation of neutral beam (NB) system for the future fusion reactor (DEMO Tokamak) has been underway between several laboratories in Europe. The spec ...

Bunch mode specific rate corrections for PILATUS3 detectors

Philip Pattison

PILATUS X-ray detectors are in operation at many synchrotron beamlines around the world. This article reports on the characterization of the new PILATUS3 detector generation at high count rates. As for all counting detectors, the measured intensities have ...
