Abstract: A design of a superconducting 3.9 GHz cavity for the in-jector of the TTF FEL-User Facility is presented. The cav-ity will be located after the first TESLA module with eight1.3 GHz cavities and before the first bunch compressor. Thepurpose of the cavity is to cancel nonlinear distortions in thelongitudinal phase space due to the cosine-like curvature ofthe 1.3 GHz accelerating cavity voltage. The basic cavityrf parameters and the properties of the higher order modescalculated with several computer codes are shown.
