Emissive cathode immersed in a plasma: plasma-cathode interactions, operation and stability
Francis Pagaud, Vincent Dolique, Nicolas Claire +1
Thermionic emission from a polycrystalline tungsten emissive cathode immersed in a magnetized plasma column is investigated experimentally and numerically. Electrical and optical m…
Nonlinear interactions of ion acoustic waves explored using fast imaging decompositions
Simon Vincent, Vincent Dolique, Nicolas Plihon
Fast camera imaging is used to study ion acoustic waves propagating azimuthally in a magnetized plasma column. The high speed image sequences are analyzed using Proper Orthogonal D…
High-speed imaging of magnetized plasmas: when electron temperature matters
Simon Vincent, Vincent Dolique, Nicolas Plihon
High speed camera imaging is a powerful tool to probe the spatiotemporal features of unsteady processes in plasmas, usually assuming light fluctuations to be a proxy for the plasma…
Laser cooling of a Planck mass object close to the quantum ground state
Leonhard Neuhaus, Remi Metzdorff, Salim Zerkani +13
Quantum mechanics has so far not been tested for mechanical objects at the scale of the Planck mass . We present an experiment where a 1 m…
Thermal noise of a cryo-cooled silicon cantilever locally heated up to its melting point
Alex Fontana, Richard Pedurand, Vincent Dolique +2
The Fluctuation-Dissipation Theorem (FDT) is a powerful tool to estimate the thermal noise of physical systems in equilibrium. In general however, thermal equilibrium is an approxi…
Suppression of surface-related loss in a gated semiconductor microcavity
Daniel Najer, Natasha Tomm, Alisa Javadi +9
We present a surface passivation method that reduces surface-related losses by almost two orders of magnitude in a highly miniaturized GaAs open microcavity. The microcavity consis…
