在多级塞曼减速器中，利用原子磁矩与随时间变化的非均匀磁场之间的相互作用，对亚稳态氖原子束进行了超声速减速。使用91次减速，原子从580 m/s的初始速度减速到105 m/s的最终速度，相当于去除了95%以上的初始动能。的相空间分布的冷，减速原子的飞行时间和成像测量，从其中的温度为10 mK的减速样品的移动帧中获得的特征。结合粒子轨迹模拟，这些测量允许减速器的相空间接受度被量化。还通过用（20）Ne和（22）Ne产生的脉冲序列进行实验，研究了通过多级塞曼减速可以实现的同位素分离程度。
A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator. Using 91 deceleration solenoids, the atoms were decelerated from an initial velocity of 580 m/s to final velocities as low as 105 m/s, corresponding to a removal of more than 95% of their initial kinetic energy. The phase-space distribution of the cold, decelerated atoms was characterized by time-of-flight and imaging measurements, from which a temperature of 10 mK was obtained in the moving frame of the decelerated sample. In combination with particle-trajectory simulations, these measurements allowed the phase-space acceptance of the decelerator to be quantified. The degree of isotope separation that can be achieved by multistage Zeeman deceleration was also studied by performing experiments with pulse sequences generated for (20)Ne and (22)Ne.
