The intrinsic toroidal velocity, Vϕ, in DIII-D (Luxon 2002 Nucl. Fusion42 614) H-modes is measured to be nonzero in the pedestal region, in the direction of the plasma current, co-Ip. Intrinsic, or spontaneous, velocity is that which arises with no known external momentum injection. This intrinsic velocity is measured to scale roughly linearly with the local ion temperature, Ti, Vϕ ∼ Ti, in the pedestal and in the edge region just inside the pedestal. With either co-Ip, or counter-Ip neutral beam injected torque, the pedestal velocity is accelerated in the direction of the torque; it is not a fixed boundary condition. A simple model of thermal ion orbit loss predicts the sign of Vϕ, a relevant magnitude for Vϕ, and the approximate scaling Vϕ ∼ Ti. This model for a boundary condition on the intrinsic toroidal velocity gives a result of approximate diamagnetic form, Vϕ ∼ εpTi/LBθ, where L is a scale length, Bθ the poloidal magnetic field and εp a small numerical parameter. This model is a local calculation of velocity, an approximation to the inherently nonlocal region of the pedestal where the thermal ion banana width is comparable to the pedestal width. In this model we also assume that the loss cone in velocity space is empty; no collisions are considered. A recent particle simulation of the pedestal region of a DIII-D NBI-driven H-mode discharge that includes collisions indicates that thermal ion orbit loss results in a co-Ip velocity just inside the last closed flux surface (Chang and Ku 2008 Phys. Plasmas15 062510-1). Thus, we do not expect that nonlocality nor finite collisionality wash out the effect. Inside the pedestal our model shows that thermal ion orbit loss is negligible. In this region of the edge we also measure a similar scaling for the intrinsic velocity several pedestal widths inside the pedestal location, Vϕ ∼ Ti. One mechanism that could maintain the Ti scaling inwards from the pedestal is the model of an inward momentum pinch velocity proportional to the gradient of Ti.
