    • Provided is a target apparatus of high durability so that a thin film is not deformed or damaged under an environment of high temperature and high pressure generated during a nuclear reaction between proton and H218O concentrate, and a productivity of 18F can be increased. The target apparatus includes a cavity member having a cavity, in which H218O concentrate is received, for producing 18F using a nuclear reaction between proton irradiated onto the H218O concentrate in the cavity and the H218O concentrate. The cavity member includes: a front opening and a rear opening facing opposite directions to each other on the irradiation path of the proton, and connected to the cavity so that the cavity can be communicated with the outside; a front thin film and a rear thin film disposed to block the front opening and the rear opening, respectively; and a front reinforcing member and a rear reinforcing member coupled to the cavity member so as to support the front thin film and the rear thin film in order to prevent the front and rear thin films from being swelled due to a pressure rising in the cavity during the nuclear reaction, wherein the front reinforcing member includes a plurality of penetration holes penetrating the front reinforcing member in the irradiation direction of the proton.
    • 提供了一种高耐久性的目标装置,使得在质子与H 2 O之间的核反应中产生的高温高压环境下,薄膜不变形或损坏, SUP浓缩物,并且可提高 18F的生产率。 目标装置包括具有空腔的空腔构件,其中容纳有H 2 O 18 O 2浓缩物,用于使用核反应产生“18” 在质子辐射到空腔中的H 2 H 2 O 20浓缩物和H 2 O 18 O 2浓缩物之间。 空腔构件包括:在质子的照射路径上彼此相对的前开口和后开口,并且连接到空腔,使得空腔能够与外部连通; 设置成分别阻挡前开口和后开口的前薄膜和后薄膜; 以及连接到空腔构件的前部加强构件和后部加强构件,以便支撑前部薄膜和后部薄膜,以防止前后薄膜由于空腔中的压力升高而膨胀 核反应,其中前加强构件包括在质子的照射方向上穿透前加强构件的多个穿透孔。
