研制了一种基于弯曲式压电驱动器驱动的旋转杠杆的旗子式原子快门，用于操纵原子束。快门标志移位约10毫米，以打开和关闭直径为5毫米的光圈，快门时间为13毫秒，产生小的机械振动。每个周期的短期快门时间稳定性为0.03 ms，平均20,000个周期的长期稳定性为0.02 ms。在超高真空室中间歇运行8个月后，快门的运行周期数（寿命）达到2.0 × 106个周期，另一个快门在大气环境中以5 Hz连续运行了2.6 × 107个周期，持续运行了60天，没有出现重大问题。经过温和的烘烤处理后，百叶窗可以在10-7 Pa的超高真空中运行。
A flag-type atom shutter based on a rotating lever that is driven by a bender piezoelectric actuator was developed to manipulate atomic beams. The shutter flag was displaced by ∼10 mm to open and close a 5-mm-diameter aperture with a shutter time of 13 ms that produced small mechanical vibrations. The short-term shutter time stability for each cycle was 0.03 ms and the long-term stability over an average of 20 000 cycles was 0.02 ms. The operational cycle number (lifetime) of the shutter reached 2.0 × 106 cycles after an intermittent operation over a period of eight months in an ultra-high vacuum chamber, and another shutter in an atmospheric environment swung for 2.6 × 107 cycles of continuous operation at 5 Hz for a period of 60 days without major problems. The shutter was shown to be compatible with the operation in an ultra-high vacuum at a low 10-7 Pa level after a gentle baking treatment.
