Preliminary design of the new FRAgment In-flight SEparator (FRAISE)

Abstract

In the next few years the existing superconducting cyclotron will be upgraded to provide ion beams with power up to 10 kW. A new FRAgment In-flight SEparator (FRAISE) has been proposed to take advantage of the higher beam power. Due to the constraint of the experimental hall shielding walls we expect to run the facility with power no higher than 3 kW. The mass of the ion available as primary beam will be lower than 70 amu. FRAISE could deliver radioactive ion beam at three experimental facilities: the magnetic spectrometer MAGNEX, the multi detector CHIMERA and the general purpose scattering chamber GIRA. Many studies will benefit from the new set-up such as: Structure of exotic nuclei, Clustering, Isospin in reaction dynamics, nuclear astrophysics (THM indirect measurement), collective resonance (GMR, GDR, PYGMY), etc.
