Charge dependence of neoclassical and turbulent transport of light impurities on MAST [PDF]
, 2015 Carbon and nitrogen impurity transport coefficients are determined from gas puff experiments carried out during repeat L-mode discharges on the Mega-Amp Spherical Tokamak (MAST) and compared against a previous analysis of helium impurity transport on ...

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties [PDF]
, 2016 The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains roughly as in the L-mode ...

The impacts and success factors of a work-from-home service-learning internship during COVID-19 [PDF]
Journal of Work-Applied Management, 2021 Purpose – COVID-19 has changed the way we teach and learn, including service-learning (S-L). This study examines the impacts of the work-from-home (WFH) mode on the work performance and learning outcomes of student interns on an eight-week S-L internship

Bare LO-Phonon Peak in THz-Emission Signals: a Dielectric-Function Analysis [PDF]
, 2002 We present a normal-mode analysis of coupled photocarrier-phonon dynamics in Te. We consider a dielectric function which accounts for LO phonons and the electron-hole gas within the Debye-Huckel model and RPA.

Quasinormal Modes of AdS Black Holes and the Approach to Thermal Equilibrium [PDF]
, 2000 We investigate the decay of a scalar field outside a Schwarzschild anti de Sitter black hole. This is determined by computing the complex frequencies associated with quasinormal modes.

Analysis of edge transport in L-mode negative triangularity TCV discharges
Nuclear Materials and Energy, 2023 One of the major problems for future tokamak devices are ELMs (Edge Localized Modes) as they can lead to large, uncontrolled heat fluxes at the machine targets. For this reason, different techniques and alternative magnetic configurations are under study to mitigate or avoid these phenomena. One of the most promising among these studies is the Negative

Global gyrokinetic simulations of intrinsic rotation in ASDEX Upgrade Ohmic L-mode plasmas
, 2018 Non-linear, radially global, turbulence simulations of ASDEX Upgrade (AUG) plasmas are performed and the nonlinear generated intrinsic flow shows agreement with the intrinsic flow gradients measured in the core of Ohmic L-mode plasmas at nominal ...
