SPLEND1D, a reduced one-dimensional model to investigate the physics of plasma detachment
O. Février, S. Gorno, C. Theiler +3
Studying the process of divertor detachment and the associated complex interplay of plasma dynamics and atomic physics processes is of utmost importance for future fusion reactors.…
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…
Parallel flows as a key component to interpret Super-X divertor experiments
M. Carpita, O. Février, H. Reimerdes +15
The Super-X Divertor (SXD) is an alternative divertor configuration leveraging total flux expansion at the Outer Strike Point (OSP). While the extended 2-Point Model (2PM) predicts…
Power exhaust and core-divertor compatibility of the baffled snowflake divertor in TCV
Sophie Gorno, Claudia Colandrea, Olivier Février +8
A baffled Snowflake Minus Low-Field Side (SF-LFS) is geometrically-optimised in TCV, increasing divertor neutral pressure, to evaluate the roles of divertor closure (comparing with…
Improved Heat and Particle Flux Mitigation in High Core Confinement, Baffled, Alternate Divertor Configurations in the TCV tokamak
Harshita Raj, C. Theiler, A. Thornton +13
Nitrogen seeded detachment has been achieved in the Tokamak a Configuration Variable (TCV) in advanced divertor configurations (ADCs), namely X-divertor and X-point target, with an…
New insights on divertor parallel flows, ExB drifts, and fluctuations from in situ, two-dimensional probe measurement in the Tokamak à Configuration Variable
H. De Oliveira, C. Theiler, O. Février +6
In-situ, two-dimensional (2D) Langmuir probe measurements across a large part of the TCV divertor are reported in L-mode discharges with and without divertor baffles. This provides…
Validation of edge turbulence codes against the TCV-X21 diverted L-mode reference case
D. S. Oliveira, T. Body, D. Galassi +27
Self-consistent full-size turbulent-transport simulations of the divertor and SOL of existing tokamaks have recently become feasible. This enables the direct comparison of turbulen…
