Abstract : This communication illustrates the technique used for the dipole moment measurement of a set of SmCo permanent magnets. These magnets have been used for the realization of a laser undulator for the ENEA-Frascati free electron laser device. The main results of the measurements are summarized. Some criteria for the assembling of the undulator are analyzed in order to minimize the effects of the differences between the magnets. The evaluation of experimental error measurement is included. Finally it is described the computer code that suggested the best configuration according to the above criteria.
