Double-resonant x-ray and microwave absorption: Atomic spectroscopy of precessional orbital and spin dynamics

Giovanni Boero, Stefano Rusponi, Pietro Gambardella

We show that double-resonance spectra recorded during the simultaneous absorption of x-ray and microwave (MW) photons are a fingerprint of the perturbed electronic configuration of atomic species driven to ferromagnetic resonance. X-ray absorption measurem ...

Towards a more reliable symmetry determination from powder diffraction: a redetermination of the low-temperature structure of 4-methylpyridine-N-oxide

The low-temperature structure of 4-methylpyridine-N-oxide was previously determined in symmetry P4(1) [Damay et al. (2006), Acta Cryst. B62, 627-633]. Using a recently published symmetry-determination method it was found that the true symmetry of the struc ...

A gamma, x-ray and high energy proton radiation-tolerant CIS for space applications

Edoardo Charbon, Herbert Shea, Lucio Carrara, Cristiano Niclass, Noémy Scheidegger

Photon counting is useful in space-based imagers wherever quantitative light- intensity evaluation is necessary. Various types of radiation, from cosmic rays to high-energy proton beams to gamma radiation, have an effect on the functionality and accuracy o ...

Neutrino signal from γ-ray-loud binaries powered by high energy protons

Mathieu Ribordy

We present a hadronic model of activity for galactic γ-ray-loud binaries, in which the multi-TeV neutrino flux from the source can be much higher and/or harder than the detected TeV γ-ray flux. This is related to the fact that most neutrinos are produced i ...

IMEX Evolution of Scalar Fields on Curved Backgrounds

Jan Sickmann Hesthaven

Inspiral of binary black holes occurs over a time-scale of many orbits, far longer than the dynamical time-scale of the individual black holes. Explicit evolutions of a binary system therefore require excessively many time-steps to capture interesting dyna ...

Phase-contrast imaging and tomography at 60 keV using a conventional x-ray tube source

Christian David

Phase-contrast imaging at laboratory-based x-ray sources using grating interferometers has been developed over the last few years for x-ray energies of up to 28 keV. Here, we show first phase-contrast projection and tomographic images recorded at significa ...

P-31 Solid-State NMR Study of the Chemical Setting Process of a Dual-Paste Injectable Brushite Cements

Jacques Lemaître

The composition and evolution of a brushite-type calcium phosphate cement was investigated by Solid-State NMR and X-ray during the setting process. The cement is obtained by mixing beta-tricalcium phosphate [Ca-3(PO4)(2), beta-TCP] and monocalcium phosphat ...

Microlensing variability in the gravitationally lensed quasar QSO 2237+0305 equivalent to the Einstein Cross II. Energy profile of the accretion disk

Frédéric Courbin, Georges Meylan, Alexander Patrick Eigenbrod

We present the continuation of our long-term spectroscopic monitoring of the gravitationally lensed quasar QSO 2237 + 0305. We investigate the chromatic variations observed in the UV/optical continuum of both quasar images A and B, and compare them with nu ...

A time-of-flight-Mott apparatus for soft x-ray spin resolved photoemission on solid samples

Luca Moreschini

We describe a new spectrometer for spin resolved photoemission from solids in the soft x-ray energy range. It is mounted on the ID08 beamline at the ESRF light source and consists of a time-of-flight (TOF) energy analyzer coupled to a retarding mini-Mott s ...

Synchrotron X-Rays for Microstructural Investigations of Advanced Reactor Materials

Manuel Alexandre Pouchon, Wolfgang Hoffelner, Maria Samaras

X-rays from synchrotron beamlines provide a powerful tool for materials analysis in circumstances where long-term materials degradation under complex loading conditions (e.g., temperature, irradiation, and stress) becomes important. This may occur for adva ...
