    "abstract": "In accelerator projects involving the use of very short bunches, such as the\nLinac Coherent Light Source (LCLS)-where the rms bunch length in the undulator\nsection is 30 micron-, it appears that even submicron imperfections in the beam\ntube surface can generate an impedance that is unacceptably large. We consider\ntwo periodic models of an imperfect, rough surface, one with small rectangular\ncorrugations, the other with smooth sinusoidal oscillations. We compare the\nimpedance of these two models.",
