23.5.2022: Improving understanding of turbulence behavior in the plasma boundary with a high heat flux ball-pen probe head
Turbulence plays an ambiguous role in tokamaks. While low turbulence levels are necessary to achieve the high-confinement regime (H-mode), some degree of turbulence in the scrape-off layer can be beneficial for power exhaust through increasing radial transport and thereby spreading heat over a wider area.

14.03.2022: Collisional radiative model for more accurate measurements of plasma parameters from a helium beam diagnostics
With a helium beam diagnostic, the local electron density and temperature at the plasma edge can be measured with high spatiotemporal resolution. For this purpose, helium is injected as a thermal beam, and the light emission resulting from the interaction with the plasma is evaluated using a collisional radiative model.
28.2.2022: Transient energy losses from I-mode plasmas in future fusion reactors
A collaboration between IPP and MIT (USA) brought new insights into relaxation events at the edge of I-mode plasmas. [more]
26.01.2022: Two young E2M scientists receive EUROfusion grants
This year two young scientists from E2M were successful in obtaining EUROfusion grants. [more]
