我们演示了由小尺寸电流导体制成的中性原子的微型化磁导的加载。冷铷原子最初储存在一个浅球形四极场中，随后通过逐渐改变捕获电位转移到磁波导中。利用电荷耦合器件相机的吸收成像原位监测了密度、温度和原子序数。在39 μ K的温度下，最初捕获的原子的14%被转移到线性微阱中。
We demonstrate the loading of a miniaturized magnetic guide for neutral atoms made of small-size current conductors. Cold rubidium atoms are initially stored in a shallow spherical quadrupole field and subsequently transferred into the magnetic guide by gradually transforming the trapping potential. Density, temperature, and atom number have been monitored iii situ by absorption imaging with a charge-coupled device camera. A fraction of 14% of the initially trapped atoms has been transferred into the linear microtrap at a temperature of 39 mu K.
