Title: Fluid analysis of the collisionless magnetohydrodynamic ballooning mode branch in tokamaks
Abstract: The stability of electromagnetic ballooning modes is investigated using a toroidal two-fluid model allowing for arbitrary Ln/LB (the characteristic scale lengths of density and magnetic-field inhomogeneities). The ballooning mode equation is solved numerically and the two-fluid and magnetohydrodynamic stability properties are discussed and compared. The perpendicular compressibility strongly reduces the growth rate and for Ln/LB∼Ln/LT∼1, the mode is completely stabilized.
