The Compact Accelerator System for Performing Astrophysical Research (CASPAR) is the only U.S. deep underground accelerator facility, with a low-background environment created by 4300 m.w.e of overhead rock shielding, suitable for low-energy nuclear astrophysics measurements. Utilizing an electrostatic acceleration system covering the energy range 150 keV to 1.1 MeV for both 1H+ and 4He+ beams, crucial reactions of interest in stellar burning are accessible in the Gamow energy range. Commissioning measurements of the CNO-cycle reaction 14N(p,γ)15O are now complete, with results presented here. CASPAR now begins to focus on reactions of interest for the production of heavy elements through the s-process, primarily the neutron source reactions for both the main and weak s-process, 13C(α,n) and 22Ne(α,n) respectively.
