Two Dimensional Grating Magneto Optical Trap in $^{\mathrm{87}}$Rb*

We demonstrate an enhanced two dimensional grating magneto optical trap with a single input beam and a planar diffraction grating. This configuration allows for an increase in experimental access when compared with a traditional two beam 2D MOT. We find a flux \textgreater 4x10$^{\mathrm{8\thinspace }}$rubidium atoms/s at a mean velocity of 18 m/s. The velocity distribution has a 3 m/s standard deviation. We use the atomic beam to load a three dimensional grating MOT with 2x10$^{\mathrm{8\thinspace }}$atoms. Methods to improve flux output will be discussed.
