    • Apparatus for radioisotope production includes housing, a plurality of target disks inside the housing and a curved windows positioned convex inward toward the disks. During operation, coolant flows though the housing across the disks and windows while electron beams passes through the window and the disks. The window temperature increases, rising the fastest in the middle of the window where the electron beam hits the window. A flat window would buckle because the center would deform during thermal expansion against the relatively unaffected periphery, but the curved window shape allows the window to endure high thermal and mechanical stress created by a combination of heating from the electron beam(s) and elevated pressure from coolant on the inside of the window. Such a window may be used for applications in which a pressurized coolant acts on only one side of the window.
    • 用于放射性同位素生产的装置包括壳体,壳体内的多个目标盘和朝向盘向内凸出的弯曲窗口。 在操作期间,冷却剂通过壳体跨过盘和窗,而电子束通过窗口和盘。 窗口温度升高,电子束撞击窗口的窗口中间最快上升。 平坦的窗口将会弯曲,因为中心在相对不受影响的周边的热膨胀期间将变形,但是弯曲的窗口形状允许窗口承受由电子束的加热和升高的压力的组合产生的高的热和机械应力 从窗口内部的冷却液。 这样的窗口可以用于其中加压的冷却剂仅作用在窗口的一侧的应用。
