摘要

我们报道了在超高真空装置中Cs原子的有效减速和俘获。在烘箱中加热的Cs原子在烘箱室后使用塞曼减速机减速，然后在科学室中使用磁光阱捕获。与传统的由炉腔内Cs原子蒸气压决定的~10-7 Pa的真空压力相比，设计的炉腔与炉腔之间采用冷短节和差压泵管，实现了~3.6×10-9 Pa的较低真空压力。这有利于在科学室内实现和保持超高真空。我们通过Cs原子的有效减速和最佳磁光阱来证明我们的装置的性能。

Effective Slowing and Trapping of Cs Atoms in an Ultrahigh-Vacuum Apparatus

We report the effective slowing and trapping of Cs atoms in an ultrahigh-vacuum apparatus. The heated Cs atoms in an oven are slowed using a Zeeman slower after the oven chamber and then trapped using a magneto-optical trap in a science chamber. Compared to the traditional vacuum pressure of ~10-7 Pa determined by the vapor pressure of Cs atoms in the oven chamber, the designed cold nipple and differential pumping tube are used between the oven and the oven chamber to achieve a lower vacuum pressure of ~3.6×10-9 Pa. This is beneficial for achieving and maintaining an ultrahigh vacuum in the science chamber. We demonstrate the performance of our apparatus through the effective slowing of Cs atoms and an optimal magneto-optical trap.
