一个简单的实验装置可以用来证明宏观尘埃颗粒在“保罗陷阱”中的储存。捕集器是在大气压力下运行的，这导致了存储粒子的有效“冷却”。在这样的条件下，一个单一的炭疽粉尘颗粒已经被限制了2个多月。当许多“冷却”的物质被捕获时，该装置非常适合于显示有序结构的形成。由于其整体简单，该设置可用于讲座，学生实验室等。
A simple experimental setup can be used to demonstrate the storage of macroscopic dust particles in a ‘‘Paul trap.’’ The trap is operated at atmospheric pressure, which results in an efficient ‘‘cooling’’ of the stored particles. Under these conditions, a single anthracene dust particle has been confined for over 2 months. The device is well suited to show the formation of ordered structures when a number of ‘‘cooled’’ species are trapped. Due to its overall simplicity, the setup can be used in lectures, student laboratories, etc.
