    • A cylindrical, convoluted, flexible bellows is used to form an atomic or molecular storage vessel with constant surface area and surface properties but adjustable volume. When utilized as a storage bulb inside an atomic or molecular frequency standard such as a hydrogen maser, it provides an apparatus for obtaining an extremely accurate measurement of the frequency deviation caused by the interaction of gas atoms (or molecules) with the vessel wall surface (i.e., the so-called ''''wall shift'''').
    • 使用圆柱形,卷积的柔性波纹管来形成具有恒定表面积和表面性质但可调节体积的原子或分子存储容器。 当用作原子或分子频率标准如氢气激光器中的储存灯泡时,它提供了一种用于获得由气体原子(或分子)与血管壁表面的相互作用引起的频率偏差的非常精确的测量的装置( 即所谓的“换城”)。

    • An apparatus is disclosed which makes use of interferometry of the matter waves accompanying particles such as neutral atoms, charged ions or electrons. The apparatus includes a particle source and a beam splitter for splitting the original beam of particles into two beams having accompanying matter waves which are coherent with each other. The two beams are recombined by a pair of beam reflectors, and the resulting interference fringes may be measured by a suitable particle detector. Such an apparatus may be used for measuring variation of the gravitational field or the rate of rotation of the apparatus. In both cases the apparatus is capable of ultra precise measurement of acceleration, of the mass of an object or the rate of rotation. Alternatively, by utilizing charged particles it is possible to measure a magnetic field to obtain a magnetometer of great sensitivity. The apparatus may finally be used to carry out holography by matter waves.
    • 公开了一种使用伴随诸如中性原子,带电离子或电子的颗粒的物质波的干涉测量的装置。 该装置包括粒子源和分束器,用于将原始粒子束分成具有彼此相干的伴随物质的两束光束。 这两个光束由一对光束反射器重新组合,并且所得到的干涉条纹可以通过合适的粒子检测器来测量。 这种装置可用于测量重力场的变化或装置的旋转速率。 在这两种情况下,该装置能够对加速度,物体质量或旋转速度进行超精密测量。 或者,通过利用带电粒子,可以测量磁场以获得高灵敏度的磁力计。 该装置最终可以用于通过物质波进行全息术。
