摘要

在太空中，由于微重力条件，使用激光冷却原子的时钟有望比在地球上有更好的性能。我们已经建造了这个太空钟的原型。在没有重力的飞机抛物线飞行中进行了测试，产生了宽度为7赫兹的原子共振，比地球上的共振窄两倍。

Test of a space cold atom clock prototype in absence of gravity

In space, thanks to micro-gravity conditions, a clock using laser cooled atoms is expected to have a better performance than on Earth. We have constructed a prototype of this space clock. It was tested in the absence of gravity of aircraft parabolic flights, yielding an atomic resonance with a width of 7 Hz, twice narrower than on Earth.
