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…
SOLPS-ITER simulation of an X-point radiator in TCV
G. Sun, O. Pan, M. Bernert +7
SOLPS-ITER simulation is performed to reproduce the X-point radiator recently observed in nitrogen-seeded TCV experiments, which is a scenario that may be favorable to solve the po…
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…
Performance assessment of a tightly baffled, long-legged divertor configuration in TCV with SOLPS-ITER
G. Sun, H. Reimerdes, C. Theiler +5
Numerical simulations explore the possibility to test the tightly baffled, long-legged divertor (TBLLD) concept in a future upgrade of the Tokamak à configuration variable (TCV). T…
Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations
Kevin Verhaegh, Aelwyn C Williams, David Moulton +7
Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion tar…
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…
X-point and divertor filament dynamics from Gas Puff Imaging on TCV
Curdin Wüthrich, Christian Theiler, Nicola Offeddu +9
A new Gas Puff Imaging (GPI) diagnostic has been installed on the TCV tokamak, providing two-dimensional insights into Scrape-Off-Layer (SOL) turbulence dynamics above, at and belo…
The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak
Kevin Verhaegh, Bruce Lipschultz, James Harrison +14
This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving and possibly play an important role as sinks of energy…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
