  In the X-ray free-elec­tron laser (XFEL), the align­ment and sta­bil­ity of beam orbit have a great im­pact on power and qual­i­ties of the gen­er­ated X-ray pulses. Cur­rently, the beam-based align­ment (BBA) is the most widely used tech­nique in beam align­ment. In order to find the best arrange­ment of quadrupoles and cor­rec­tors, a math­e­mat­i­cal model is es­tab­lished based on the trans­mis­sion ma­trix method. With this model, sev­eral sim­ple arrange­ments of quadrupoles and cor­rec­tors are se­lected to sim­u­late the beam align­ment process. It is found that when two cor­rec­tors ad­just two quadrupoles, the beam can pass through the cen­ter of quadrupoles ap­prox­i­mately col­li­mated.
