Knife edge skimming for improved separation of molecular species by the deflector
摘要:
描述了一种用于成形分子束的刀刃,以通过静电偏转器改善分子束中物质的空间分离。改进了不同分子种类彼此之间以及与原子种子气体的空间分离。在相互作用区中的选定分子束部分的柱密度,其对应于较高的信号速率,被增强了1.5倍,受限于分子束的虚拟源尺寸。
英文摘要:
A knife edge for shaping a molecular beam is described to improve the spatial separation of the species in a molecular beam by the electrostatic deflector. The spatial separation of different molecular species from each other as well as from atomic seed gas is improved. The column density of the selected molecular-beam part in the interaction zone, which corresponds to higher signal rates, was enhanced by a factor of 1.5, limited by the virtual source size of the molecular beam.
