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 کاملthe role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Low 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...
