The SECAR (SEparator for CApture Reactions) recoil separator, recently commissioned at the Facility for Rare Isotope Beams (FRIB), enables direct measurements of the relevant proton- and α-capture reactions. SECAR takes advantage of radioactive beams produced by FRIB via projectile fragmentation, which are then stopped, and reaccelerated to astrophysical energies at the ReA3 facility. Reactions are studied in inverse kinematics by impinging the beam on a H or He target in gaseous or solid form. The reaction recoils are counted at SECAR, where a sequence of magnets and velocity filters separate them from the unreacted beam.
I will present the astrophysical motivation for SECAR's development and the results from measurements that were performed with SECAR during commissioning in 2021.
