Abstract： The linear behavior of the double tearing mode driven by anomolous electron viscosity effects associated with magnetic braiding is investigated within the framework of MHD. A two-space-scale analysis is performed and the result is used to obtain an approximate dispersion relation for the mode. If the seperation of the rational surfaces at x =±xs is sufficiently small, xs/ α<<(kyα)-11/15R-1/15, the growth rate is predicted to scale as R-1/15. With increa-sing seperation the mode makes a transition to R-1/3 scaling, where R = τv/τH. The R-1/5 scaling is shown to be correlated with violation of the constant-φ approximation.
