Description
The Separator for Capture Reactions (SECAR), under construction at Michigan State University, is a next-generation recoil separator system optimized for nuclear astrophysics measurements with radioactive ion beams at the National Superconducting Cyclotron Laboratory (NSCL) and at the Facility for Rare Isotope Beams (FRIB). SECAR will enable the measurement of critical proton and alpha radiative capture reactions on proton-rich unstable nuclei that are needed to improve our understanding of stellar explosions such as novae, supernovae, and X-ray bursts. Two +/-300 kV Wien filters with carefully matched electric and magnetic effective field length are used to achieve beam rejection compatible with the high radioactive beam intensities expected from FRIB/ReA.
The design philosophy, status of SECAR construction, the early commissioning plans and the first commissioning measurements at MSU NSCL/FRIB will be presented.
