Abstract

We report on an efficient and compact high-flux Cs atom beam source based on a retro-reflected two-dimensional magneto-optical trap (2D MOT). We realize an effective pushing field component by tilting the 2D MOT collimators towards a separate three-dimensional magneto-optical trap (3D MOT) in ultra-high vacuum. This technique significantly improved 3D MOT loading rates to greater than 8×1098 \times 10^9 atoms/s using only 20 mW of total laser power for the source. When operating below saturation, we achieve a maximum efficiency of 6.2×10116.2 \times 10^{11} atoms/s/W.
