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…
A novel understanding of the role of plasma-molecular kinetics on divertor power exhaust
N. Osborne, K. Verhaegh, D. Moulton +12
During detachment, a buffer of neutral atoms and molecules builds up between the target and the ionising plasma. Collisions between the plasma and the molecules play an important r…
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…
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…
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…
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…
Tomographic reconstruction of the runaway distribution function in TCV using multispectral synchrotron images
T. A. Wijkamp, A. Perek, J. Decker +8
Synchrotron radiation observed in a quiescent TCV runaway discharge is studied using filtered camera images targeting three distinct wavelength intervals. Through the tomographic S…
Runaway electron synchrotron radiation in a vertically translated plasma
M. Hoppe, G. Papp, T. Wikjamp +6
Synchrotron radiation observed from runaway electrons (REs) in tokamaks depends upon the position and size of the RE beam, the RE energy and pitch distributions, as well as the loc…
