Influence of the dynamic ergodic divertor on the density limit in TEXTOR.
A significant influence of the dynamic ergodic divertor (DED) on the density limit in TEXTOR has been found. In Ohmic discharges, where without DED detachment normally arises at the density limit, a MARFE (multifaceted asymmetric radiation from the edge) develops when the DED is operated in a static regime. The threshold of the MARFE onset in the neutral beam heated plasmas is increased by appl...
متن کاملFractal structure of the magnetic field in the laminar zone of the Dynamic Ergodic Divertor of the Torus Experiment for Technology-Oriented Research „TEXTOR-94..
Magnetic field properties at the plasma edge in the Dynamic Ergodic Divertor ~DED! for the Torus Experiment for Technology Oriented Research ~TEXTOR-94! @Fusion Eng. Des. 37, 337 ~1997!# have been studied. This is done by using a generalized symplectic mapping method of integration of field line equations. It is shown that by the radial shift of the resonant magnetic surfaces implemented by cha...
متن کاملLow frequency heating and flow driven by the dynamic ergodic divertor in tokamaks
The profile and dissipation of the field excited by dynamic ergodic divertor (DED) coils in tokamak plasmas are calculated, and an estimate is made of the poloidal/toroidal velocities driven by this field. The coils are idealized as an inboard sheet current composed of a toroidal sequence of helical line current segments expanded in Fourier series with poloidal/toroidal mode numbers M/N , and m...
متن کاملNumerical modelling of pump limiter biasing on TEXTOR - 94 and Tore Supra
The two-dimensional multifluid code TECXY has been used to model the biasing (with respect to the first wall) of the toroidal belt limiter ALT-II on the tokamak TEXTOR-94 and of the new toroidal pump limiter being installed on Tore Supra tokamak in the framework of the CIEL project. It is well known that the edge flow pattern can be influenced by the poloidal electric drifts from imposing radia...
متن کاملPFC / JA - 94 - 35 Performance of the Alcator C - Mod Closed Divertor in Ohmically Heated Plasmas
Alcator C-Mod operation with a single null closed divertor produces clean, Zeff <1.3 plasmas and two dissipative divertor regimes. For ;1e > 0.7x 1020 m3 the divertor plasma is highly recycling and radiative with high densities and low temperatures near the strike points. If the temperature near the target plates drops to <5 eV, this plasma detaches from the plates over most of their surfaces. ...
