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.

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.
