§1.一种新型低温H2/D2靶生产系统 我们在核科学实验室GeV-γ实验大厅建造了一台名为FOREST[1]的4πγ射线探测器。 FOREST 用于研究基本反应，例如 N(γ,π0)X。氢/氘 (H2/D2) 目标在我们的研究中很重要。我们需要构建适合 FOREST 探测器的 H2/D2 目标。首先，我们使用低温恒温器在小型真空室中构建了固体氢靶。然后，我们用一个新的真空室在各种条件下做了很多测试，计划在我们的实验中使用它。我们已经成功地制造了固体氢靶材。新型低温 H2/D2 靶系统由三部分组成：气体冷却系统、保护低温恒温器免受热辐射的隔热罩以及真空室。图1显示了该系统的示意图。
§1. A New Cryogenic H2/D2 Target Production System We have constructed a 4π γ-ray detector named FOREST [1] in the GeV-γ experimental hall at Laboratory of Nuclear Science. The FOREST is used for the study of elementary reactions such as N(γ,π0)X. A hydrogen/deuterium (H2/D2) target is important in our study. We need to construct the H2/D2 target fitted to the FOREST detector. At first, we constructed a solid hydrogen target in a small vacuum chamber, using a cryostat. Then, we have made many tests under various conditions with a new vacuum chamber, which is planned to be used in our experiments. We have succeeded in making a solid hydrogen target. The new cryogenic H2/D2 target system consists of three parts: a gas cooling system, a heat shield defending a cryostat from heat radiation, and a vacuum chamber. Figure 1 shows a schematic view of the system.
