In the field of precision measurement such as atom interferometers and atom gyros, the most basic and important step was to obtain cold atoms. When experiments require continuous and highly reproducible measurements, the faster loading rate of cold atoms will be required. In order to load cold atoms faster, a high-flux, low-speed cold atomic beam was required. A 2D cooling system of 87Rb atoms based on 2D-MOT+push beam scheme was built, the 3D-MOT loaded from the 2D-MOT was measured and a loading rate of 2.8×109 atoms/s was achieved. Two pairs of cooling beams with two mirrors with λ/4 coating were implemented. The beams were transformed into a shape which had an ellipse profile with 25 mm short axis and 75 mm long axis, by using cylindrical lenses.
