Hybrid-Vlasov–Maxwell simulations of magnetized plasma turbulence including non-linear electron-inertia effects in a generalized Ohm's law are presented. When fluctuation energy is injected on scales sufficiently close to ion-kinetic scales, the ions efficiently become de-magnetized and electron-scale current sheets largely dominate the...

The main goal in the HOLMES experiment is the neutrino mass measurement using an array of 1000micro-calorimeters with standard metallic absorber. A good isotope for such measurement is the163Ho, those isotopes embedded in the metallic absorber will be 1011-1013. Since163Ho is not available in nature, a dedicated process must be set up to...

The European Research Council has recently founded HOLMES, an experiment for a direct neutrino mass measurement with a sensitivity as low as 0.4 eV. HOLMES will perform a calorimetric measurement of the the energy released in the Electron Capture (EC) spectrum of 163Ho. The neutrino mass is assessed from the end point of the spectrum; the...
