An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
Cross-Calibration and First Vertical ECE Measurement of Electron Energy Distribution in the TCV Tokamak
A. Tema Biwole, L. Porte, A. Fasoli +8
This paper describes the first Vertical Electron Cyclotron Emission (V-ECE) measurement of non-thermal electron distributions in the \textit{Tokamak à Configuration Variable}, TCV.…
First numerical analysis of runaway electron generation in tungsten-rich plasmas towards ITER
J. Walkowiak, M. Hoppe, I. Ekmark +7
The disruption and runaway electron analysis model code was extended to include tungsten impurities in disruption simulations with the aim of studying the runaway electron (RE) gen…
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…
Fluid and kinetic studies of tokamak disruptions using Bayesian optimization
Ida Ekmark, Mathias Hoppe, Tünde Fülöp +4
When simulating runaway electron dynamics in tokamak disruptions, fluid models with lower numerical cost are often preferred to more accurate kinetic models. The aim of this work i…
