铷原子的低速束是从二维磁光阱或原子漏斗中产生的。来自热束的原子被啁啾激光冷却减慢，然后被装入漏斗。冷原子被移动的糖蜜喷射出来，糖蜜是由频移的激光束形成的。产生的原子束具有3至10 m/s范围内的可控速度，500 µK的温度和1010原子/s的通量。
A low-velocity beam of rubidium atoms is produced from a two-dimensional magneto-optic trap or atomic funnel. Atoms from a thermal beam are slowed by chirped laser cooling and then loaded into the funnel. The cold atoms are ejected by moving molasses formed with frequency-shifted laser beams. The resultant atomic beam has a controllable velocity in the range of 3 to 10 m/s, a temperature of 500 µK, and a flux of 1010 atoms/s.
