Using two frequency domain and one time domain numerical approaches, the authors calculate the short-range longitudinal wakefield of the NLC linac accelerating structure, and find that the results agree to {approx} 5%. In addition they obtain, through fitting, a simple formula for the short-range wakefield of a linac structure that can be useful in designing linear colliders. Finally, they demonstrate that for the NLC linac cavity the effects on the short-range wake of end conditions, tapering, and rounding of the irises are small.
