    • An x-ray window includes a mount with a support frame and an aperture. A window film has a stack of layers including: a thin film layer comprising a material selected from the group consisting of diamond, graphene, diamond-like carbon, beryllium, and combinations thereof; a boron hydride layer; and a polymer layer. The window film, including the thin film layer, the boron hydride layer, and the polymer layer, extends across the aperture and is supported by the support frame. The window film is attached to the support frame, defining a sealed joint. The layers are capable of withstanding a differential pressure of at least 1 atmosphere. The window film is substantially transmissive to x-rays having an energy in the range of 100-20,000 electronvolts.
    • X射线窗口包括具有支撑框架和孔的安装座。 窗膜具有一叠层,包括:薄膜层,其包含选自金刚石,石墨烯,类金刚石碳,铍及其组合的材料; 硼氢化物层; 和聚合物层。 包括薄膜层,硼氢化物层和聚合物层的窗膜延伸穿过孔并由支撑框架支撑。 窗膜附接到支撑框架,限定密封接头。 这些层能承受至少1个大气压的差压。 窗膜对具有在100-20,000电子伏特范围内的能量的x射线基本上是透射的。

    • A neutron chopper according to the present invention includes a housing which internally forms a sealed space, the housing having window portions through which neutrons pass, a fixed shaft which is fixed inside the housing, a rotor which is rotatably supported by the fixed shaft, the rotor provided with a blocking portion which can block neutrons passing through the housing, and a motor which is provided inside the housing for rotating the rotor of the neutron chopper, where a stator of the motor is fixed to the fixed shaft, and a rotor of the motor receives a rotating force from the stator around the fixed shaft, and is fixed to the rotor of the neutron chopper. The neutron chopper is formed with small size, and neutron guides are easily disposed closely, consequently vacuum leak is hardly occurred in the neutron chopper.
    • 根据本发明的中子切碎机包括内部形成密封空间的壳体,所述壳体具有中子通过的窗口部分,固定在壳体内部的固定轴,由固定轴可旋转地支撑的转子, 转子,其设置有阻挡穿过壳体的中子的阻挡部分;以及电动机,其设置在壳体内部,用于使中子切断器的转子旋转,其中电动机的定子固定到固定轴;转子, 电机从定子绕固定轴接收旋转力,并固定在中子切碎机的转子上。 中子斩波器形成为小尺寸,并且中子引导件容易紧密地设置,因此在中子斩波器中几乎不发生真空泄漏。
