SL-I constructed by CAEP is a linear induction accelerator which will produce a 20MeV,3kA,60ns electron beam. The high performance required for the machine is connected to the beam quality and thus closely to the accelerator alignment.In order to minimize corkscrew motion and emittance increase of the beam, the stretched wrie technique has been developed to measure precisely magnetic axes of cavities: the dipole steering magnets have been equipped in cavities to correct their misalignments: the laser tracker has been used to examine the installation of the accelerator. In this paper,the different alignment techniques have been presented and discussed but also the first results have been obtained.
