Power in Plasma RF heating in a tokamak cavity 1

We consider the problem of computing the global response of a tokamak to RF-antenna driving, including conversion at the ion-hybrid resonance layer. The tokamak is modeled as a 2-D circular cavity (a poloidal cross-section). An antenna launches a family of magnetosonic (MS) rays. The amplitude and phase of the MS wave eld are transported using eikonal techniques: the phase is transported using ...

BIASING OF SINP - TOKAMAK PLASMA IN HIGH - q REGIME

In SINP-TOKAMAK [an iron-core device having major radius = 30 cm, minor radius = 7.5 cm and B(toroidal) = 2 Tesla(maximum)] both high/normal q and very low q (VLQ) regimes can be achieved. Recently in this machine fast edge biasing experiment in the later regime revealed a change in plasma current profile at edge region leading to better confinement and longer duration of plasma current. The co...
