Abstract
In order to keep the gain reduction of the TTF VUV-FEL (Conceptual Des ign Report, Germany, 1995, Ref. [1]) smaller than 15%, the electron be am has to be aligned in the undulator within 12 mu m rms. One method o f aligning the beam uses the technique of beam-based alignment. In thi s paper, the applicability region of this method is investigated. The influence of unknown, random dipole kicks due to the error in the plan ar undulator structure and kicks due to quadrupole offsets are discuss ed. (C) 1998 Elsevier Science B.V.
