Fundamental properties of exotic nuclei, far from the valley of beta-stability, such as their ground-state mass, are crucial to our understanding of the nucleon-nucleon interaction and the behaviour of the nuclear many-body system. Radioactivebeam studies are thus currently one of the most exciting challenges of nuclear physics and astrophysics.The predictive power of mass models developed from stable nuclei can be greatly improved, and thus the limits of existence of nuclei determined, by extending mass measurements to the most exotic nuclei. Crucial data are also missing to account for the abundances of nuclides along the path of the nucleosynthesis r-process.I have previously developed an original and direct method using the GANIL CSS2 cyclotron as a high-resolution spectrometer. The proposed research aims to develop a new technique exploiting the unique capability of the new SPIRAL cyclotron to reach the masses of more exotic nuclei, initially along the N=Z line to study neutron-proton pairing and test the CVC hypothesis of the standard model of the electro-weak interaction. Key to its success is the automatic cyclotron radiofrequency sweeping, which will require a programme of technical development as well as the minimisation of systematic errors to attain the necessary high precision.
