A compact approach to higher-resolution resonant inelastic x-ray scattering detection using photoelectrons
Henrik Moodysson Rønnow, Markus Scholz
The detection of inelastically scattered soft x-rays with high energy resolution usually requires large grating spectrometers. Recently, photoelectron spectrometry for analysis of x-rays (PAX) has been rediscovered for modern spectroscopy experiments at sy ...
Iop Publishing Ltd2024Data for "Ultrafast deep-ultraviolet study of photoexcited aqueous Ferrioxalate"
Majed Chergui, Christoph Bostedt, Michele Puppin, Malte Oppermann
Data repository for the following publication: A. Duque-Prata*, H.-Y. Chen*, L. Müller, M. Oppermann, M. Puppin, C. Serpa, C. Bostedt and M. Chergui, “Ultrafast deep-ultraviolet study of photoexcited aqueous Ferrioxalate”, submitted to ChemPhotoCh ...
Zenodo2023PID-like active impedance control for electroacoustic resonators to design tunable single-degree-of-freedom sound absorbers
Hervé Lissek, Maxime Volery, Xinxin Guo
Sound absorption at low frequencies still remains a challenge in both scientific research and engineering practice. Natural porous materials are ineffective in this frequency range, as well as acoustic resonators which present too narrow bandwidth of absor ...
2022Application of Thomson scattering to helicon plasma sources
Ivo Furno, Patrick Blanchard, Alan Howling, Yanis Andrebe, Rémy Jacquier, Riccardo Agnello, Alban Sublet
The possibility of performing electron density and temperature measurements in a high power helicon plasma is a crucial issue in the framework of the AWAKE (Advanced WAKefield Experiment) project, which demonstrates acceleration of particles using GeV m(-1 ...
2020Inverse design and demonstration of high-performance wide-angle diffractive optical elements
Diffractive optical elements are ultra-thin optical components required for constructing very compact optical 3D sensors. However, the required wide-angle diffractive 2D fan-out gratings have been elusive due to design challenges. Here, we introduce a new ...
OPTICAL SOC AMER2020Correcting the extended-source calibration for the Herschel-SPIRE Fourier-transform spectrometer
We describe an update to the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) Fourier-transform spectrometer (FTS) calibration for extended sources, which incorporates a correction for the frequency-dependent far-field feedhorn efficiency, eta(ff ...
2018Quantifying the Limits of Detection of Surface-Enhanced Infrared Spectroscopy with Grating Order-Coupled Nanogap Antennas
Hatice Altug, Andreas Tittl, Aurélian Michel John-Herpin
Infrared spectroscopy is widely used for biomolecular studies, but struggles when investigating minute quantities of analytes due to the mismatch between vibrational cross sections and IR wavelengths. It is therefore beneficial to enhance absorption signal ...
2018The thermal triple-axis-spectrometer EIGER at the continuous spallation source SINQ
EIGER is the new thermal triple-axis-spectrometer at the continuous spallation SINQ at PSI. The shielding of the monochromator consists only of non- or low magnetizable materials, which allows the use of strong magnetic fields with the instrument. This shi ...
Elsevier2017An operando emission spectroscopy study of Pt/Al2O3 and Pt/CeO2/Al2O3
In situ time-resolved spectroscopic examination of catalysts based on well dispersed nanoparticles on metal oxides under transient conditions significantly facilitates the elucidation of reaction mechanisms. In this contribution, we demonstrate the level o ...
