扫频荧光法测量超高真空原子磁光阱中的磁场分布
Measuring the Magntic-field Gradient in an Ultrahigh Vacuum MOT through Observing Fluorescence While Laser Frequency Sweeping
摘要
利用扫频荧光法实测了超高真空原子吸收池中反亥姆霍兹线圈轴线上的磁场分布,与计算结果对比,同时还采用移动暗线的测量方法进行了检验.考虑到封接材料的非线性磁化,可以解释所有观察到的现象.
Abstract
The magnetic-field gradient in axis of an ant-Helmholtz coil in a dilute Rb vapor through observing fluorescence while laser frequency sweeping is measured. The result is checked by using other method and is compared with the calculation. All phenomena could be understanded by considering nonlinear magnetic susceptibility.
