Efficiency of LH+EC Current Drive in Tokamaks Featuring an Internal Transport Barrier
LH+EC Current Drive Tokamaks an Internal Transport Barrier
2010/10/14
In the present paper we study the effects due to the occurrence of radial transport of particles in a tokamak on the efficiency of current drive due to combined action of lower hybrid waves and electr...
Non-Twist Field Line Mappings for Tokamaks with Reversed Magnetic Shear
Non-Twist Field Line Mappings Tokamaks Reversed Magnetic Shear
2010/10/27
The structure of magnetic field lines in a tokamak with reversed magnetic shear is investigated by means of analytically derived area-preserving non-twist Poincar´e maps. The basic configuration...

Radial Transport the LH Current Drive Efficiency Tokamaks an Internal Transport Barrier
2010/10/27
In the present paper we study the effects of occurrence of radial transport of particles in a tokamak, and the effects of the presence of an Internal Transport Barrier (ITB), on the current drive effi...
Parallel Permittivity Elements for Radio Frequency Waves in Elongated D-shaped Tokamaks
Parallel Permittivity Elements Radio Frequency Waves Elongated D-shaped Tokamaks
2010/10/27
Parallel permittivity elements are derived for radio-frequency waves in an axisymmetric tokamak with D-shaped transverse cross-sections of the magnetic surfaces under arbitrary aspect ratio, arbitrary...
