摘　　要：The construction of a two-dimensional magneto–optical trap with hollow cooling and pushing（2D-HP MOT） is reported in detail,and a velocity-tunable cold atomic beam produced by this 2D-HP MOT is demonstrated.The magneto–optical trap system,which is constructed by a transparent quartz tube,is low in price,easy to fabricate and assemble,and convenient for atomic trapping and detection.The mean axial velocity of the cold atomic beam can be tuned from 4.5 to 8 m/s,while the atomic flux remains at a level of 1010 atoms∕s.This cold atomic beam source can be applied in the areas of high-precision measurements based on cold atoms.The construction of a two-dimensional magneto–optical trap with hollow cooling and pushing（2D-HP MOT） is reported in detail,and a velocity-tunable cold atomic beam produced by this 2D-HP MOT is demonstrated.The magneto–optical trap system,which is constructed by a transparent quartz tube,is low in price,easy to fabricate and assemble,and convenient for atomic trapping and detection.The mean axial velocity of the cold atomic beam can be tuned from 4.5 to 8 m/s,while the atomic flux remains at a level of 1010 atoms∕s.This cold atomic beam source can be applied in the areas of high-precision measurements based on cold atoms.
