N1 - Funding Information:
The DRAGON group would like to thank Bob Laxdal and the ISAC operators help and support in providing the ion beam as well as the TRIUMF technical brought the DRAGON to life. The work was done with the financial support and the DOE.

N2 - In the modelling of nucleosynthesis in nova explosions, temperature and density are important parameters to describe the hydrodynamics. Those parameters are not easy to observe, but specific gamma-ray emitters produced in the explosion provide constrains on the models, such as 22Na, produced via 21Na(p,Υ 22Mg(β+)22Na. The new DRAGON recoil separator facility, designed and built to measure directly the rates of radiative proton and alpha capture reactions, important for nuclear astrophysics, is now operational. Experiments have been conducted on the 21Na(p,γ)22Mg reaction using a radioactive 21Na beam incident onto a windowless hydrogen gas target. Yield measurements have been performed detecting the prompt gamma and the reaction recoils at Ecm ≈ 821 keV and 204 keV.
