摘要:

我们描述了一种利用脉冲原子或分子束来绘制静电场、静磁场和射频磁场的空间变化的技术。该方法是使用一个设计用于测量电偶极矩的电子束演示。我们提出的相互作用区域的地图,显示灵敏度(i)电场变化1.5 V/cm,3.3 kV/cm的空间分辨率为15 mm;(ii)磁场变化5 nT,25 mm的分辨率;(iii)射频磁场幅度与15 mm的分辨率。这种新的诊断技术是非常强大的背景下,高精度的原子和分子物理实验,脉冲束迄今尚未发现广泛的应用。

英文摘要:

We describe a technique for mapping the spatial variation of static electric, static magnetic, and rf magnetic fields using a pulsed atomic or molecular beam. The method is demonstrated using a beam designed to measure the electric dipole moment of the electron. We present maps of the interaction region, showing sensitivity to (i) electric field variation of 1.5 V/cm at 3.3 kV/cm with a spatial resolution of 15 mm; (ii) magnetic field variation of 5 nT with 25 mm resolution; (iii) radio-frequency magnetic field amplitude with 15 mm resolution. This new diagnostic technique is very powerful in the context of high-precision atomic and molecular physics experiments, where pulsed beams have not hitherto found widespread application.
