用于具有表面电极离子阱的离子捕获的模块化低温恒温器

Modular cryostat for ion trapping with surface-electrode ion traps

Grahame Vittorini, Kenneth Wright, Kenneth R. Brown, Alexa W. Harter, S. Charles Doret

摘要:

我们提出了一个简单的低温恒温器的目的与表面电极离子阱使用,设计一个负担得起的,大的冷却功率的商业脉冲管制冷机。具有单个真空空间的模块化真空外壳便于内部访问,并实现快速周转和灵活性,以备将来修改。长矩形窗口在离子阱的平面中提供近360度的光学访问,而阱附近的圆形底部窗口使得能够在不需要真空光学器件的情况下进行NA 0.4光收集。我们评估系统的机械和热特性,我们量化离子捕获性能捕获40 Ca+,发现小杂散电场,长离子寿命,和低离子加热速率。

英文摘要:

We present a simple cryostat purpose built for use with surface-electrode ion traps, designed around an affordable, large cooling power commercial pulse tube refrigerator. A modular vacuum enclosure with a single vacuum space facilitates interior access, and enables rapid turnaround and flexiblity for future modifications. Long rectangular windows provide nearly 360 degrees of optical access in the plane of the ion trap, while a circular bottom window near the trap enables NA 0.4 light collection without the need for in-vacuum optics. We evaluate the system's mechanical and thermal characteristics, and we quantify ion trapping performance by trapping 40Ca+, finding small stray electric fields, long ion lifetimes, and low ion heating rates.
