ABSTRACT The paper presents the first time‐dependent SOLPS‐ITER modeling of a transition to the X‐point radiator (XPR) regime in ASDEX Upgrade tokamak with nitrogen seeding and its subsequent stabilization using a numerical feedback scheme. The feedback control loop allows to stabilize the …

The early stages of X-point radiator (XPR) regime formation in a medium-size metal-wall tokamak with a single-null configuration and vertical divertor targets are discussed in detail, using the ASDEX Upgrade tokamak as an example. Based on the SOLPS-ITER modeling of ASDEX Upgrade …

Abstract In the paper a SOLPS-ITER modeling of H-Mode scenarios with different seed impurity gases (N, Ne, Ar, Kr) is performed for ASDEX Upgrade geometry. These gases are compared from the point of view of their radiation efficiency and compression in the …

Abstract For the first time, an X-point radiating (XPR) regime using neon (Ne) seed impurity has been obtained in ITER modelling with the SOLPS-ITER code, including fluid drifts. The highly radiating pattern is qualitatively similar to those observed experimentally in ASDEX Upgrade …

In this paper SOLPS-ITER simulations of Ar and N seeded discharges are presented for H-mode conditions on ASDEX Upgrade and for burning plasmas on ITER. These discharges are additionally compared with Ne seeded cases for both tokamaks. It is demonstrated that Ar …

Abstract A simple analytical model for the estimation of scrape-off-layer (SOL) electron temperature profile in the equatorial outer midplane (OMP) is suggested. It is demonstrated that the OMP electron temperature profile in the SOL can be approximated by a power function of …

SOLPS-ITER code simulations with fluid drifts activated are used to examine the consequences for divertor performance, under burning plasma conditions, of a reduction in scrape-off layer (SOL) cross-field transport such that the outboard midplane SOL parallel heat flux width, λq is reduced …
