摘要：
本文讨论了一种利用樟脑升华将粒子从钨探针尖端直接释放到捕获区域，从而选择性装载粒子到磁重力阱中的技术。这种升华激活释放（SAR）装载技术利用带有钨探针尖端的微定位器，以及樟脑在室温下相对较快的升华速率，选择性装载直径范围从 $\SI{8}{\micro \meter}$ 到 $\SI{100}{\micro \meter}$ 或更大的粒子。该方法的优点包括：能够选择性装载独特粒子或供应有限的粒子；与替代技术相比损耗低；粒子释放时速度低；设计灵活，允许装载到具有复杂几何形状的阱中。本文通过将粒子装载到磁重力阱中演示了 SAR 技术，但该技术也可适用于其他悬浮光力学系统。
英文摘要：
In this paper we discuss a technique for selectively loading a particle into a magneto-gravitational trap using the sublimation of camphor to release particles from a tungsten probe tip directly into the trapping region. This sublimation-activated release (SAR) loading technique makes use of micropositioners with tungsten probe tips, as well as the relatively fast rate of sublimation of camphor at room temperature, to selectively load particles having diameters ranging from $\SI{8}{\micro \meter}$ to $\SI{100}{\micro \meter}$ or more. The advantages of this method include its ability to selectively load unique particles or particles in limited supply, its low loss compared to alternative techniques, the low speed of the particle when released, and the versatility of its design which allows for loading into traps with complex geometries. SAR is demonstrated here by loading a particle into a magneto-gravitational trap, but the technique could also be applicable to other levitated optomechanical systems.
