Validation of geometric proxies using negative and positive triangularity plasmas with varying elongation on TCV and multi-machine gyrokinetic simulations
Alessandro Balestri, Justin Ball, Stefano Coda +7
Negative Triangularity (NT) tokamak plasmas can achieve H-mode-like confinement while avoiding Edge Localized Modes, making them an attractive reactor scenario. Predicting in which…
Two-length spatial correlation function of turbulence in TCV
Olivier Panico, Pascale Hennequin, Sascha Rienäcker +4
Spatial correlation functions of density fluctuations are measured in the Tokamak à Configuration Variable (TCV) using a dual-channel Doppler backscattering (DBS) diagnostic. In ce…
First step toward multi machine ELM energy scalings and extrapolations to SPARC and ITER
R. Perillo, A. Redl, T. Eich +14
It is shown that the ELM energy loss normalized by the plasma stored energy (ΔEELM/Wplasma) for high-density small/QCE ELM regimes scales inversely with the separatrix turbulence p…
High-power TCV scenario for conventional and alternative divertor studies
K. Lee, C. Theiler, M. Carpita +20
Alternative divertor configurations (ADCs) must be evaluated under boundary plasma conditions approaching reactor-level values to be considered a reliable, physics-based solution f…
Detachment dynamics and disturbance rejection in the TCV X-Point Target divertor
M. Winkel, K. Verhaegh, B. Kool +11
The X-Point Target divertor is an alternative divertor configuration with a secondary X-point in its divertor volume. In this work, we investigate the dynamic response and disturba…
Infrared Thermography in the Tokamak à Configuration Variable
M. Zurita, H. Reimerdes, C. Colandrea +9
In the Tokamak à Configuration Variable (TCV), infrared thermography (IR) is currently composed of the horizontal, vertical, and tangential infrared systems (HIR, VIR, TIR), which…
Expulsion of runaway electrons using ECRH in the TCV tokamak
J. Decker, M. Hoppe, U. Sheikh +19
Runaway electrons (REs) are a concern for tokamak fusion reactors from discharge startup to termination. A sudden localized loss of a multi-megaampere RE beam can inflict severe da…
Towards practical reinforcement learning for tokamak magnetic control
Brendan D. Tracey, Andrea Michi, Yuri Chervonyi +15
Reinforcement learning (RL) has shown promising results for real-time control systems, including the domain of plasma magnetic control. However, there are still significant drawbac…
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…
An improved understanding of the roles of atomic processes and power balance in divertor target ion current loss during detachment
Kevin Verhaegh, Bruce Lipschultz, Basil Duval +16
The process of divertor detachment, whereby heat and particle fluxes to divertor surfaces are strongly diminished, is required to reduce heat loading and erosion in a magnetic fusi…
Fluctuation characteristics of the TCV snowflake divertor measured with high speed visible imaging
N. R. Walkden, B. Labit, H. Reimerdes +6
Tangentially viewing fast camera footage of the low-field side snowflake minus divertor in TCV is analysed across a four point scan in which the proximity of the two X-points is va…
Impurity seeding for suppression of the near Scrape-Off Layer heat flux feature in tokamak limited plasmas
F. Nespoli, B. Labit, I. Furno +5
In inboard-limited plasmas, foreseen to be used in future fusion reactors start-up and ramp down phases, the Scrape-Off Layer (SOL) exhibits two regions: the "near" and "far" SOL.…
