Momentum transport and plasma rotation spin up in TCV
This paper reports on the experimental observation of toroidal rotation braking and plasma spin up due to the growth and decay of Magnetohydrodynamic (MHD) modes in the Tokamak à Configuration Variable (TCV) operated in the ohmic regime. The results of numerical simulations of momentum spin up, with the goal of evaluating the momentum diffusion coefficient Dφ , are also presented. Unlike most e...
متن کاملGlobal Plasma Oscillations in Electron Internal Transport Barriers in TCV
Global plasma oscillations have been observed in the Tokamak à Configuration Variable (TCV; R/a=0.88m/ 0.25m, BT<1.54T) in reversed magnetic shear discharges (fully non-inductive driven) with electron Internal Transport Barriers (eITBs). These slow oscillations involve the electron temperature and density and the plasma current. The triggering mechanism is the periodic destabilisation and stabi...
متن کاملOptical properties of relativistic plasma mirrors
The advent of ultrahigh-power femtosecond lasers creates a need for an entirely new class of optical components based on plasmas. The most promising of these are known as plasma mirrors, formed when an intense femtosecond laser ionizes a solid surface. These mirrors specularly reflect the main part of a laser pulse and can be used as active optical elements to manipulate its temporal and spatia...
متن کاملReal-time optical plasma boundary reconstruction for plasma position control at the TCV tokamak
A dual, high speed, real-time visible light camera setup was installed on the TCV tokamak to reconstruct optically and in real-time the plasma boundary shape. Localized light emission from the plasma boundary in tangential view, broadband visible images results in clearly resolved boundary edge-features. These projected features are detected in real-time and transformed to the poloidal plane to...
متن کاملCarbon transport in TCV
Knowledge of the impurity transport parameters and their relation with those of the main plasma particles is important for predicting the fusion performance of a tokamak reactor and provides an element for validating advanced transport models currently under development. The radial profiles of fully ionized carbon C (transition n=8-7, 529.1 nm) released from TCV (R = 0.88 m, a<0.25m, BT<1.5 T) ...
