Spectroscopic characterisation of TCV divertor towards a detached regime

The challenge of power exhaust of the high heat and particle fluxes foreseen for ITER and the forthcoming nuclear fusion reactors can be mitigated by operating in a detached divertor regime.This regime has been the object of three decades of studies, as it ...

Electron spectrometer calibration method

Tobias Kippenberg, Fabrizio Carbone, Alexey Sapozhnik, Yujia Yang, Thomas La Grange, Arslan Sajid Raja

The present invention concerns an energy dispersion calibration method for calibrating an electron spectrometer of an electron spectrometer system including at least one electron emission source, electron optics and the electron spectrometer. The method co ...

Measurement of the 171Tm beta spectrum

Lesya Shchutska, Alexey Boyarsky

The beta spectrum of the main transition of the 171Tm was measured using a double focalizing spectrometer. The instrument was lately improved in order to reduce its low energy threshold to 34 keV. We used the spectrometer to measure the energy end-point of ...

Importance of 3D radiative transfer effects on high-resolution NO2 remote sensing in cities

Marc Damien Schwärzel

Urban air quality is a major concern in the context of human health since cities are at the same time emission hot spots and home to a large fraction of the world's population. Airborne imaging spectrometers may be a valuable addition to traditional air po ...

Spectrometer-free electron probe of ultrafast thermal dynamics in optically excited samples

Fabrizio Carbone

Cutting edge electron microscopes allow to probe the optical excitations in nanostructures with subangstrom spatial and femtosecond temporal resolution. In this study we discuss the prospects of probing the ultrafast out-of-equilibrium dynamics of plasmoni ...

Constraining the response factors of an extractive electrospray ionization mass spectrometer for near-molecular aerosol speciation

Julia Schmale, Imad El Haddad, Yandong Tong

Online characterization of aerosol composition at the near-molecular level is key to understanding chemical reaction mechanisms, kinetics, and sources under various atmospheric conditions. The recently developed extractive electrospray ionization time-of-f ...

In-line electronic and structural characterization of reactively sputtered Cu-Co-Mn black spinel oxides

Andreas Schueler, Anna Krammer, Maxime Lagier

Cu-Co-Mn spinel oxide thin films are deposited by reactive magnetron sputtering. The x-ray diffraction (XRD) spectrum suggests a nanocrystalline spinel film when sputtered at approximate to 465 degrees C. In-line scanning tunneling microscopy confirms nano ...

Ug-value and edge heat loss of triple glazed insulating glass units:A comparison between measured and declared values

Andreas Schueler, Anna Krammer

Triple glazed low-e coated insulating glass units with argon filling of five different suppliers on the European market with a declared thermal transmittance in the undisturbed centre of glass (Ug-value) of 0.6 W/m(2)K have been purchased from resellers an ...

Measurement of the muon flux from 400 GeV/c protons interacting in a thick molybdenum/tungsten target

Lesya Shchutska, Aurelio Bay, Guido Haefeli, Elena Graverini, Alexey Boyarsky, Federico Leo Redi, Maria Elena Stramaglia, Oleg Ruchayskiy, Nikolaos Charitonidis, Jean-Loup Tastet, Ekaterina Kuznetsova, Hans Dijkstra, Anton Petrov, Sergei Smirnov

The SHiP experiment is proposed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. About 1011muons per spill will be produced in the dump. To design the experiment s ...

Spin cascade and doming in ferric hemes: Femtosecond X-ray absorption and X-ray emission studies

Majed Chergui, Oliviero Cannelli, Christopher Alexander Arrell, Wojciech Gawelda, Giulia Fulvia Mancini, Frederico Alves Lima, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Rebecca Ann Ingle, Jérémy Raymond Jean Maurice Rouxel, Samuel Menzi

The structure-function relationship is at the heart of biology, and major protein deformations are correlated to specific functions. For ferrous heme proteins, doming is associated with the respiratory function in hemoglobin and myoglobins. Cytochrome c (C ...
