Impact of triangularity on edge transport and divertor detachment: a SOLPS-ITER study of TCV L-mode plasmas
Fabio Mombelli, Andrea Mastrogirolamo, Elena Tonello +7
Negative triangularity (NT) magnetic configurations have recently gained attention as a promising route to achieve H-mode-like confinement without edge-localized modes (ELMs) and w…
Tungsten erosion and scrape-off layer transport modelling in L-mode helium plasma discharges in ASDEX Upgrade
G. Alberti, E. Tonello, C. Tuccari +13
Due to its unavoidable presence in thermonuclear DT plasmas and to its peculiar effects on materials, investigating the role of helium (He) in plasma-wall interaction (PWI) in curr…
Modelling of power exhaust in TCV positive and negative triangularity L-mode plasmas
E. Tonello, F. Mombelli, O. Février +10
L-mode negative triangularity (NT) operation is a promising alternative to the positive triangularity (PT) H-mode as a high-confinement ELM-free operational regime. In this work, t…
Investigating the influence of divertor baffles on nitrogen-seeded detachment in TCV with SOLPS-ITER simulations and TCV experiments
G. Sun, H. Reimerdes, C. Theiler +8
Plasma edge simulations with the SOLPS-ITER code are performed to study the influence of divertor baffles on nitrogen-seeded detachment in TCV single-null, L-mode discharges. Scans…
Comparison of detachment in Ohmic plasmas with positive and negative triangularity
O. Février, C. K. Tsui, G. Durr-Legoupil-Nicoud +18
In recent years, negative triangularity (NT) has emerged as a potential high-confinement L-mode reactor solution. In this work, detachment is investigated using core density ramps…
