Design of Computer Controlling and Acquiring-data System For Constant Scaled Energy Atomic Spectroscopy

报道了用于电场中高激发态原子常数标度能谱实验研究的计算机控制、采集系统 ,对系统的各个主要模块及功能实现方法进行了阐述。该系统对能量E和电场F进行实时控制 ,以在扫描过程中保持标度能ε=E/F为常数 ,并用该系统首次成功地得到了Sr原子在标度能ε=- 3.0时的光谱。

A computer control and acquisition system for studying the constant scaled energy spectroscopy for atom in external electric field was demonstrated and described.The system controls the excitation energy E and the strength of the electric field F in real time to keep the scaled energy ε=E/F constant during scanning E and F .With this system, constant scaled energy spectra of Strontium atoms at ε= -3.0 in a static electric field were successfully recorded for the first time.
