Radial Profile and Confinement of Energetic Particles during NBI and ICRF Heating in LHD

The energetic ion distributions and confinements are studied in the LHD plasma applying a newly developed radial profile measurement system FICXS (Fast Ion Charge Exchange Spectroscopy) based on the Doppler shifted Balmer-alpha (Hα) emission from the energetic ions charge-exchanged with injected neutral beams. A clear difference is found in the Hα emission spectrum changing the magnetic configu...

Energetic Charged Particles Above Thunderclouds

The French government has committed to launch the satellite TARANIS to study transient coupling processes between the Earth’s atmo­ sphere and near-Earth space. The prime objective of TARANIS is to detect energetic charged particles and hard radiation emanating from thunderclouds. The British Nobel prize winner C.T.R. Wilson predicted lightning discharges from the top of thunderclouds into spac...

Solar flares and energetic particles.

Solar flares are now observed at all wavelengths from γ-rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares. Energetic electrons and ions interact with the solar atmosphere and produce high-energy X...
