Hou, Shunyong Wang, Qin Deng, Lianzhong Yin, Jianping Dependence of guiding efficiency on the curvature radius of the filter <p><strong>Figure 6.</strong> Dependence of guiding efficiency on the curvature radius of the filter. The data with an error bar and the solid curve are yielded from 3D Monte Carlo simulations and theoretical calculations, respectively.</p> <p><strong>Abstract</strong></p> <p>We propose a scheme of a surface electrostatic velocity filter capable of preparing cold polar molecules on the surface of a substrate by selecting a low-velocity component of an effusive beam from a thermal gas reservoir. Using ND<sub>3</sub> as a molecular sample, the dependence of the performance of the filter on the parameters of both the filter setup and the incident molecular beam is investigated by using a theoretical model and Monte Carlo simulations. A detailed study of the guiding process of molecules, including the evolution of phase space density of the packet in the filter, is carried out and shows that the beam selection process is mainly completed in the front part of the filter.</p> velocity filter;filter setup;front part;gas reservoir;nd;phase space density;beam selection process;error bar;3 D Monte Carlo simulations;Monte Carlo simulations;curvature radius;Atomic Physics;Molecular Physics 2013-06-26
