We re-study the one-dimensional electric held structure of an Outer gap accelerator by considering the physical limit of trans-field height. Inside the outer gap, the charge depletion creates a large electric held along the magnetic held lines. Electrons and/or positions are accelerated to ultra-relativistic energies by this longitudinal electric held, and then radiate gamma-ray photons by curvature radiation. The collision of these gamma-rays and ambient x-ray photons further produce radiating particles, resulting in a stationary gap. We solve the structure of this longitudinal electric held together with the distributions of elections and positions and gamma-ray photons for an aligned rotator. Our results indicate that the outer gap can extend to the light cylinder using reasonable parameters.
