Detailed results are presented from the first experimental study of self-regulation between plasma relative density fluctuations and perpendicular velocity over limit cycle oscillations (LCO) across the edge and near scrape-off layer (SOL) regions of the MAST-U spherical tokamak. The start of the dithering phase is preceded by the localisation of t…

This work examines the separatrix and SOL characteristics in three scenarios on JET: the Quasi-Continuous Exhaust (QCE) regime, the core-edge-SOL integrated ITER Baseline scenario, and the X-point Radiator (XPR) regime. All three scenarios are potentially compatible with reactor operations, as they aim to provide power exhaust solutions through dif…

This paper presents a comprehensive user study aimed as assessing and differentiating operator expertise within bilateral teleoperation systems. The primary objective is to identify key performance metrics that effectively distinguish novice from expert users. Unlike prior approaches that focus primarily on psychological evaluations, this study emp…

AC losses in the high temperature superconducting (HTS) toroidal field (TF) magnets of the STEP tokamak are analysed, focusing on the transient electromagnetic response of the centre column to the charging and discharging of the central solenoid (CS) and poloidal field (PF) magnets during a plasma initiation scenario. An innovative H-H…

The DEMO fusion reactor Divertor design group within the EUROfusion consortium use RCC-MRx as the main analysis code for the Divertor’s structural integrity assessment. Analysis has been carried out within the same group using an in-house developed Finite Element Analysis post processing script which follows the Design by Elastic Analysis rule…

ERMES 20.0 is an open-source software which solves the Maxwell’s equations in frequency domain with the Finite Element Method (FEM). The new ERMES 20.0 is a significant upgrade from the previous ERMES 7.0. It introduces new features, modules, and FEM formulations to address the challenging problems commonly encountered in the design and analysis …

Parametric study of main flow characteristics in magnetohydrodynamic flow in the exit pipe from a liquid metal blanket has been performed. The flow in such a duct occurs in a nonuniform, decreasing magnetic field. The duct wall is electrically conducting. The wall conductance ratio, c, and the gradient of the field, γ, have been varied in a wide r…

A Gas Electron Multiplier (GEM) based detector was exploited for the first time on the MASTU tokamak during the 2023 campaign to investigate Soft X-Ray (SXR) radiation (1-20keV) emitted from the plasma. SXR radiation carries essential information on electron temperature and density, impurity presence, and Magneto-hydrodynamic (MHD) activities, m…
