Super Séparateur Spectromètre

The S3 project, is a device designed for experiments with the very high intensity stable heavy ion beams of the accelerator of the SPIRAL2 Project at GANIL. S3 is designed to combine high acceptance, a high degree of primary beam rejection, and high mass resolving power to enable new opportunities in several physics domains in nuclear physics and atomic physics. The spectrometer comprises large aperture superconducting multipole triplets, 3 magnetic dipoles, and 1 electrostatic dipole arranged as a momentum achromat followed by a mass separator. Various detection set-ups are under construction, especially a delayed spectroscopy array (SIRIUS), a low energy branch (LEB) and an atomic physics collider (FISIC).
