The study of ultracold atoms and molecules, and their interactions is one of the most active areas of physics research. However, these studies have been limited by the techniques used to cool the atoms and molecules. This SGER project will develop a new method for slowing paramagnetic atoms and molecules using rapidly switched pulsed magnetic fields. The specific goal of this project is to slow and stop beams of atomic hydrogen and deuterium ad to trap them in a magnetic quadrupole trap. Initial optimization of the experiment will be done with metastable neon, which is easier to detect. The broader impact of this work is the development of a magnetic slower that will enable trapping of any paramagnetic atom or molecule. The research project will directly support two graduate students. Additional undergraduate students will work on the project.

对超冷原子和分子及其相互作用的研究是物理学研究中最活跃的领域之一。然而，这些研究受到用于冷却原子和分子的技术的限制。 这个SGER项目将开发一种新的方法，使用快速切换的脉冲磁场来减缓顺磁性原子和分子。这个项目的具体目标是减慢和停止原子氢和氘的光束，并将它们捕获在磁四极阱中。 实验的初始优化将使用亚稳态氖进行，亚稳态氖更容易检测。 这项工作的更广泛的影响是开发了一种磁性减速器，可以捕获任何顺磁性原子或分子。 该研究项目将直接支持两名研究生。 更多的本科生将参与该项目。
