分子束方法与加速器物理学方法的结合产生了操纵分子运动的新工具。在过去的几年里，中性分子的减速器、透镜、聚束器、陷阱和储存环已经被证明。具有可调速度和可调速度分布宽度的分子束现在可以产生，并且有望成为各种物理化学和化学物理实验中的有价值的工具。在这里，我们提出了一个紧凑的分子束机器，能够产生3D空间聚焦包的状态选择的加速或减速的分子。
The merging of molecular beam methods with those of accelerator physics has yielded new tools to manipulate the motion of molecules. Over the last few years, decelerators, lenses, bunchers, traps, and storage rings for neutral molecules have been demonstrated. Molecular beams with a tunable velocity and with a tunable width of the velocity distribution can now be produced, and are expected to become a valuable tool in a variety of physical chemistry and chemical physics experiments. Here we present a compact molecular beam machine, capable of producing 3D spatially focused packets of state-selected accelerated or decelerated molecules.
