27.9.2019: Characterisation of Highly Radiating Plasmas with Neon
In future fusion devices a large fraction of the power has to be dissipated by electromagnetic radiation before it damages the divertor targets.  The puffing of impurities like neon into the plasma increases the radiation, but also might impact the plasma's stability. [more]
12.7.2019: First light from the novel Thomson scattering diagnostics in the divertor of ASDEX Upgrade
After several years of planning and construction, the new diagnostics at ASDEX Upgrade provided data for the first time for plasma discharge #36597. [more]
08.05.2019: Advanced analysis of electron cyclotron emission measurements
Two PhD candidates dedicated their work to the investigation and exploitation of electron cyclotron emission radiation emitted by the plasma confined in a tokamak. [more]
11.04.2019: Experimental determination of boron transport properties in ASDEX Upgrade plasmas
The transport properties of boron ions in ASDEX Upgrade plasmas have been determined experimentally and compared to theoretical predictions. This information is important to the success of the fusion program, as future magnetic confinement fusion reactors will have to control the transport of both low- and high-Z elements in the plasma in order to produce net fusion power.

6.3.2019: EUROfusion Engineering Grant awarded to young E2M Scientist
Each year, EUROfusion awards a series of Researcher and Engineering grants to promising young scientists working on fusion research in Europe. E2M young scientists are no strangers to these grants, as was reported already in 2017 and 2018. This year, one such successful applicant is Rodrigo Arredondo, who applied to the topic of ‘Analysis of tritium inventory and permeation in DEMO plasma-facing components’. [more]
4.2.2019: The Influence of Radiation, Mechanical, and Plasma-Induced Damage on Deuterium Retention in Tungsten
The role of specific defects on deuterium retention in tungsten was clarified in dedicated laboratory experiments. Such information is important because hydrogen isotopes are retained in tungsten only by bonding to lattice defects and this finally determines tritium retention in plasma-facing components in fusion reactors.
