我们提出并表征了一个通用的实验装置，它允许在量子气体中的里德伯原子的激发和检测。该装置的新概念具有两个带电粒子探测器和真空室内的八个电场板，可以检测和操纵里德伯原子。这里提出的设置适用于量子气体领域中使用的所有原子种类。我们描述和表征玻色-爱因斯坦凝聚体的生产，激发方案到里德伯态，里德伯态的检测场电离，然后由离子检测和各种电场配置提供的8个场板。
We present and characterize a versatile experimental setup which allows for excitation and detection of Rydberg atoms in quantum gases. The novel concept of the setup features two charged particle detectors and eight electrical field plates inside the vacuum chamber, which allows the detection and manipulation of Rydberg atoms. The setup presented here is applicable to all atomic species used in the field of quantum gases. We describe and characterize the production of Bose-Einstein condensates, the excitation scheme into Rydberg states, the detection of Rydberg states by field ionization followed by ion detection and the various electric field configurations provided by the eight field plates.
