论文摘要
我们表明，在没有其他真空抽水机制的情况下，微型加工的非蒸发Getter泵（NEGS）可以延长激光冷却原子可以在磁光陷阱（MOT）中产生的时间。在第一项研究中，Weimine将硅玻璃微生物超高真空（UHV）带有硅蚀刻的腔腔和铝尼硅硅酸盐（ASG）窗口，并证明了单个激活的否定的否定的零件在10分钟内反复加载MOT。在第二项研究中，进一步研究了用激光激活的neg材料的被动泵送的能力，进一步研究了含有五个NEG片剂的硼硅酸盐吹制的比色杯细胞。在这个单元格中，MOT在没有外部主动泵系统的情况下保持了4天以上的可见。这个MOT观察时间超过了几乎数量级在无耶和华场景中获得的时间。通过否定材料使细胞的可伸缩性和潜在的真空寿命可能使您的微型冷原子仪器的发展能够使其发展。
We show that micro-machined non-evaporable getter pumps (NEGs) can extend the time over which laser cooled atoms canbe produced in a magneto-optical trap (MOT), in the absence of other vacuum pumping mechanisms. In a first study, weincorporate a silicon-glass microfabricated ultra-high vacuum (UHV) cell with silicon etched NEG cavities and alumino-silicateglass (ASG) windows and demonstrate the observation of a repeatedly-loading MOT over a 10 minute period with a single laser-activated NEG. In a second study, the capacity of passive pumping with laser activated NEG materials is further investigated ina borosilicate glass-blown cuvette cell containing five NEG tablets. In this cell, the MOT remained visible for over 4 days withoutany external active pumping system. This MOT observation time exceeds the one obtained in the no-NEG scenario by almostfive orders of magnitude. The cell scalability and potential vacuum longevity made possible with NEG materials may enable inthe future the development of miniaturized cold-atom instruments.
