Highlights 2023

Research news from the division Plasma Edge and Wall

4.7.2023: Forward-looking studies on heat removal for reactor concepts successfully carried out at ASDEX Upgrade
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]
01.06.2023: Unexpected isotopic dependence of access threshold found for high energy confinement plasmas
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]
08.05.2023: Insight into L-H transition physics through high resolution E<sub>r</sub> measurements in the plasma edge of ASDEX Upgrade
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]
11.4.2023: New discovery points the way to more compact fusion power plants
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]
22.3.2023: E2M scientist receives EUROfusion grant
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]
01.02.2023: Investigation of the heat load on the first wall in ASDEX Upgrade for ITER scenarios
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]
