Overview of lower single-null neutral beam heated ELMy H-mode plasmas in TCV

Recent experimental studies on the medium sized TCV tokamak, a carbon device featuring an open divertor, focus on the physics of the type-I H-mode in lower single-null plasmas. This regime, known to provide a good confinement but intolerable transient target heat loads in ITER, is now routinely achieved in TCV with the installation of a 1MW neutral beam injector. While pedestal parameters are estimated from the upgraded Thomson scattering diagnostics, heat loads at the inner and outer targets are measured by infrared thermography and complemented by Langmuir probe measurements.
