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 have developed several instruments, including a blow-in type windowless gas target and an ionization chamber.Experiments were performed at Ecm= 2.4 and 1.5 MeV using the developed instruments and the cross sections were obtained. A hybrid detector employing both an ionization chamber and a Si-SSD detector was developed to reduce the carbon backgrounds more efficiently. It was found that the new detector could reduce the background ratio by three orders,and the experiments in Ecm<1.2 MeV were ready for carrying out

九州大学串联实验室（KUTL）计划采用直接16 O探测方法测量反应能量从Ecm= 2.4到0.7 MeV的截面。为了进行该实验并获得关于截面的定量信息，误差在10%以内，我们开发了几种仪器，包括吹气式无窗气体靶和电离室，在Ecm= 2.4和1.5MeV下进行了实验，获得了截面。为了更有效地减少碳背景，研制了一种采用电离室和Si-SSD检测器的混合检测器。结果表明，该探测器可使本底比降低三个数量级，为开展Ecm<1.2MeV的实验做好了准备
