| Abstract: | The mechanism of spatial resonance of Alfven waves for heating a collisionless plasma is studied in the presence of a twisted
magnetic field. In addition to modifying the equilibrium condition for a cylindrical plasma, the azimuthal component of the
magnetic field gives extra contribution to the energy deposition rate of the Alfven waves. This new term clearly brings out
the effects associated with the finite lifetime of the Alfven waves. The theoretical system considered here conforms to the
solar coronal regions. |
