A recoil separator in combination with a windowless gas target has been designed for the measurement of the radiative capture reaction p(7Be, γ)8B. The separator consists of momentum and velocity filters and a ΔE-E detector telescope. The setup was tested quantitatively using the p(12C, γ)13N reaction at the effective energy Ecm= 841 keV. Projectile fluxes were measured directly with Faraday cups and indirectly with elastic backscattering into Si detectors, while the13N recoil flux was measured directly with the ΔE-E telescope. A suppression of the12C beam particles by a factor 2 × 10-10was observed when the system was tuned for the recoil13N's. Special emphasis was given to the charge state probabilities of the13N recoils. Possible improvements of the system for the measurement of other capture reactions are discussed.
