Special mechanical experiments have shown that the differences in deformation behaviour between cold and hot worked or unworked tungsten are due to a change in microstructure during working. [more]
One of the greatest challenges of fusion research on tokamaks is to achieve optimal plasma energy confinement while minimising the heat load on the reactor walls. The 'Quasi Continuous Exhaust' regime - QCE for short - promises to combine both aspects. [more]
Unique experiments with plasmas containing tritium at the JET fusion facility in Culham, UK, show that plasmas made from mixtures of hydrogen isotopes behave differently from isotopically pure plasmas of the same isotopic weight. [more]
The formation of the edge radial electric field (Er) was investigated experimentally at ASDEX Upgrade in L-modes of favourable and unfavourable drift configuration prior to confinement transitions. [more]
A magnetic cage keeps the more than 100 million degree Celsius hot plasmas in nuclear fusion devices at a distance from the vessel wall so that they do not melt. [more]
This year two young scientists from IPP working on edge physics in tokamaks were successful in obtaining EUROfusion grants, one of them being E2M. [more]
Turbulence at the plasma edge is advantageous for material-friendly power dissipation. It suppresses excessively steep temperature and density profiles at the plasma edge and thus avoids undesired instabilities, so-called edge localised modes (ELMs). [more]
