[en] This paper describes the setting up of ray-tracing tools and preliminary beam dynamics studies concerning the electron model 3-5.4463 MeV of a non-linear, non-scaling proton driver FFAG 3-10 GeV. Its contents is as follows: 1. Introduction; 2. Fields and cell parameters; 3. First order results; 4. Dynamical aperture; 5. Conclusion; Appendix: A Zgoubi data file. In conclusion one stresses that a more exhaustive investigation could be carried out as based upon the results obtained. Similar investigations could also be carried out on the proton driver. Further steps would include acceleration and full transmission studies as it has been performed in the isochronous muon ring and its electron model
