论文摘要
扫描量子低温原子显微镜（SQCRAMSCOPE）是一个量子传感器，其中从附近样品中发出的准1D量子量子图像电磁场。我们报告了显微镜的改进。通过用闭合周期系统和改性的冷手指代替液体低温恒温器来降低低温，而低温冷却通过添加辐射罩来增强。最低可访问的样品温度从35 K降低到5.8 K，同时保持较低的样品振动。新的样品安装座更容易交换，并且精简了量子气体。
The Scanning Quantum Cryogenic Atom Microscope (SQCRAMscope) is a quantum sensor in which a quasi-1D quantum gas images electromagnetic fields emitted from a nearby sample. We report improvements to the microscope. Cryogen usage is reduced by replacing the liquid cryostat with a closed-cycle system and modified cold finger, and cryogenic cooling is enhanced by adding a radiation shield. The minimum accessible sample temperature is reduced from 35 K to 5.8 K while maintaining low sample vibrations. A new sample mount is easier to exchange, and quantum gas preparation is streamlined.
