Experimental investigation on ionized ultracold molecules formed in a magneto-optical trap by time-of-flight mass spectroscopy

摘要: 利用飞行时间质谱探测了由磁光阱中的俘获光和再泵浦光光缔合作用形成的超冷基态铯分子，研究了微通道板工作电压、加速电场强度和加速电场持续时间对铯分子离子信号强度的影响．实验结果与理论模型的拟合一致；获得了适合实验条件的最优化实验参数，为进一步研究超冷分子的光缔合光谱和光电离光谱奠定了实验基础．

Abstract: We use time-of-flight mass spectroscopy to detect the ultracold ground state Cs2 molecules formed directly by a photoassociation due to the trapping laser beams and repumping laser beam in a magneto-optical trap. We investigate the dependences of the Cs+ intensity on operating voltage of micro-channel-plate, accelerating field intensity and duration time of the accelerating field. The experimental results are consistent with theoretical fitting. We obtain the best optimal parameters suited to our experimental condition, which is important for the future experiment on ultracold molecule photoassociation and photoionization spectroscopy.
