A cross section measurement employing a direct 16O detection method for the reaction energies from Ecm = 2.4 to 0.7 MeV is planned at Kyushu University Tandem Laboratory (KUTL). To perform this experiment and to obtain quantitative information about the cross section to within an error of 10%, we developed several instruments in 2009, including a blow-in type windowless gas target and movable slits for the recoil mass separator. A target thickness of 24×3.9 Torr cm was achieved using the developed gas target. Trajectories in the recoil mass separator were analyzed to reduce the background generated by scattered 12C ions. Experiment at Ecm = 2.4 MeV was performed using these instruments and the cross section was obtained. Experiment at Ecm =1.5 MeV was started and first result was obtained.
