The ALTO facility is powered by a 50 MeV/10μA linear electron accelerator dedicated to the production of radioactive beams. The production mode is based on the photo-fission process of a thick UCx target heated up to 2000°C and using the ISOL technique. For the ionization of the released fission fragments, three ion source types can be coupled to the target: Febiad ion source, surface ion source, and laser ion source. The facility can deliver the radioactive ions beams to six different experimental set-ups. The mono-charged RIB exiting from the source must be separated using a magnetic dipole in order to select a nucleus before its transmission through electrostatic devices up to the experimental set-ups. This paper is focus on the separator which was build and exploited with success since 40 years. We propose to revisit this dipole with a precise field-map calculation and particles transport simulations. These results will be use as a first brick of the understanding and reliability of the transmission along the RIB lines at the ALTO facility.
