Abstract: K04.00002 : Direct measurements of astrophysical reactions using the DRAGON recoil separator*
2:06 PM–2:42 PM
To overcome these challenges, the DRAGON (Detector of Recoils And Gammas Of Nuclear Reactions) recoil spectrometer at the TRIUMF-ISAC Radioactive Ion Beam Facility has been designed to directly measure radiative capture reactions of importance for nuclear astrophysics in inverse kinematics [1,2]. To date DRAGON still holds the record for the number of direct measurements of radiative capture reactions performed with radioactive ion beams world-wide.
In this contribution, I will give a brief overview of specifications and operation of the DRAGON recoil separator before presenting recent experimental highlights including the first direct measurement of an astrophysical reaction using a radioactive beam of isomeric nuclei, as well as future upgrades to the facility.
