我们演示了使用由两个平行的带电导线和两个接地的金属板组合产生的中空静电场引导超音速重水（D2O）分子束，并报告了一些新的和初步的实验结果。在实验中，我们利用飞行时间质谱的方法检测了束流导向信号，并研究了束流导向器的相对传输率与导向电压的关系。研究表明，随着引导电压Vguid的增加，束流波导的相对透过率呈线性增加，当引导电压为+20.0kV时，被引导的D2O分子数至少增加了89.4%。最后，简要讨论了我们的导引方案在分子光学中的一些潜在应用。
We demonstrate the guiding of a supersonic heavy-water (D2O) molecular beam using a hollow electrostatic field generated by the combination of two parallel charged-wires and two grounded metal-plates, and report some new and preliminary experimental results. In the experiment, we detect the guiding signals by using the method of time-of-flight mass spectrum and study the dependence of the relative transmission of the beam guide on the guiding voltage. Our study shows that the relative transmission of the beam guide is increased linearly with increasing guiding voltage Vguid, and the number of the guided D2O molecules is at least increased by 89.4% when the guiding voltage is +20.0 kV. Finally, some potential applications of our guiding scheme in the molecule optics are briefly discussed.
