    • A clock including: a portable, at least partially evacuated housing; a cell being positioned within the housing and including an internal cavity having interior dimensions each less than about 1 millimeter, an intra-cavity pressure of at least about 760 Torr, and containing a metal atomic vapor; an electrical to optical energy converter being positioned within the housing to emit light through the metal atomic vapor; an optical energy intensity detector being positioned within the housing to receive the light emitted by the converter through the metal atomic vapor; at least one conductive winding around the cavity to stabilize the magnetic field experienced in the cavity dependently upon the detector; and, an output to provide a signal from the housing dependently upon the detector detecting the light emitted by the converter through the metal atomic vapor.
    • 时钟包括:便携式,至少部分撤离的房屋; 细胞位于所述壳体内并且包括具有小于约1毫米的内部尺寸,至少约760托的腔内压力并且包含金属原子蒸汽的内部空腔; 电 - 光能转换器位于壳体内以通过金属原子蒸气发光; 光能量强度检测器定位在壳体内以接收由转换器通过金属原子蒸汽发射的光; 围绕腔体的至少一个导电绕组,以依赖于检测器来稳定腔体中经历的磁场; 以及输出,用于根据检测器检测由转换器通过金属原子蒸气发射的光来提供来自壳体的信号。
