Improved alternating gradient transport and focusing of neutral molecules
摘要：
极性分子，在强场寻求状态下，可以通过电场梯度的交替序列来传输和聚焦，所述电场梯度在一个横向方向上聚焦，而在另一个横向方向上散焦。我们显示，通过计算和数值模拟，如何可以大大提高交替梯度传输和聚焦的分子。我们使用一个新的优化多极透镜设计，FODO晶格光束传输线，和透镜匹配的光束传输线的光束源和最终的焦点。我们推导出解析表达式的潜力，字段和梯度，可用于设计这些镜头。我们描述了一个简单的透镜优化过程，并推导出跟踪分子通过光束传输线的运动方程。作为一个例子，我们建立了一个直的光束线，传输560米/秒的射流源束的甲基氟化物15米，从它的源，并将其聚焦到2毫米直径。我们计算的光束传输线的接受和光束的生存，与速度扩散的光束，并估计指定的源条件下的传输强度。讨论了可能的应用。
英文摘要：
Polar molecules, in strong-field seeking states, can be transported and focused by an alternating sequence of electric field gradients that focus in one transverse direction while defocusing in the other. We show, by calculation and numerical simulation, how one may greatly improve the alternating gradient transport and focusing of molecules. We use a new optimized multipole lens design, a FODO-lattice beam transport line, and lenses to match the beam transport line to the beam source and to the final focus. We derive analytic expressions for the potentials, fields, and gradients that may be used to design these lenses. We describe a simple lens optimization procedure and derive the equations of motion for tracking molecules through a beam transport line. As an example, we model a straight beamline that transports a 560 m/s jet-source beam of methyl fluoride15 m from its source and focuses it to 2 mm diameter. We calculate the beam transport line acceptance and beam survival, for a beam with a velocity spread, and estimate the transmitted intensity for specified source conditions. Possible applications are discussed.
