A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the energy frontier. Offering a combination of unprecedented energy collisions in a comparatively clean leptonic environment, a high energy muon collider has the unique ...
Iop Publishing Ltd2024Lightning interaction with the ionosphere
Marcos Rubinstein, Dongshuai Li
Lightning discharges, including cloud-to-ground (CG) and intracloud (IC) lightning, are known to emit electromagnetic pulses (EMPs) in a wide frequency band ranging from few Hz up to hundreds MHz [1]. During the breakdown and ionization processes (mostly f ...
IET2023EMC and earthing concept of the ITER EC-system
Damien Fasel, Ugo Siravo, Jérémie Dubray, Francisco Sanchez
Gyrotrons and High Voltage Power Supplies (HVPS) used on electron cyclotron (EC) systems are the source of large electromagnetic interference (EMI). Arcing events inside gyrotrons is the most frequently cited issue, but fast shutdown of a HVPS can produce ...
ELSEVIER SCIENCE SA2023Correction of spherical surface measurements by confocal microscopy
Toralf Scharf, Wilfried Noell, Jeremy Béguelin
Refractive microlenses are nowadays widely used in optical systems. Characterizing their surface is essential to ensure their quality and to optimize their fabrication process. This is realized by optical surface profilers thanks to their vertical resoluti ...
2020Disruption Prediction Approaches Using Machine Learning Tools in Tokamaks
Nuclear fusion is one of the best options to achieve a virtually limitless energy source in the future. However, sustaining burning plasma reactions is very challenging because disruptive events cause the loss of plasma confinement and damages to the tokam ...
IEEE2019Composition of the low seismic velocity E ′ layer at the top of Earth's core
Using ab initio simulations on Fe-Ni-S-C-O-Si liquids, we constrain the origin and composition of the low-velocity layer E′ at the top of Earth's outer core. We find that increasing the concentration of any light element always increases velocity and so a ...
2017Cubic zirconia in >2370◦C impact melt records Earth’s hottest crust
Bolide impacts influence primordial evolution of planetary bodies because they can cause instantaneous melting and vaporization of both crust and impactors. Temperatures reached by impact-generated silicate melts are unknown because meteorite impacts are e ...
Elsevier2017From 2D to 3D Characterization of Materials Subjected to Extreme Pressure and Temperature Conditions
Planetesimal were the first planetary objects to form in the solar system, which later grew to make the proto-planets. Most of these bodies were differentiated as a result of internal heating. Several differentiated bodies have, then, been accreted followi ...
EPFL2017Chemical Characterisation of Deep Earth Reservoirs
Seismic imaging of the internal Earth has emphasized the inhomogeneity of its mantle. This interface layer of nearly 3000 km surrounding the central metallic core conducts heat released from the latter, which played a significant role in shaping the actual ...
EPFL2016Light confinement effect of non-spherical nanoscale solid immersion lenses
Hans Peter Herzig, Gaël David Osowiecki, Toralf Scharf, Myun Sik Kim, David Nguyen
We report on the light confinement effect observed in non-ideally shaped (i.e., non-spherical) nanoscale solid immersion lenses (SILs). To investigate this effect, nanostructures of various shapes are fabricated by electron-beam lithography. When completel ...
