In this work, we show experimental evidences, confirmed by numerical results, from type-Il intermittency in the driven Double Scroll Circuit. Numerically, we found a new scaling power law dependence on the critical parameter. This result is a consequence of the new global bifurcation scenario for the T-2 torus breakdown observed in this system: a homoclinic saddle connection is the nonlinear mechanism responsible for the reinjection of the trajectory around a repelling focus. In fact, in this global scenario the total laminar phase is the spiraling laminar period (usually considered) plus the time the trajectory spends in the vicinity of the saddle points.
