Ultracold atoms provide exciting opportunities for precision measurements and testing fundamental physics. Two-dimensional(2D) magneto-optical traps(MOT) are advantageous in faster loading to 3D-MOTs and cooling more atoms. However, compact and power-efficient setups are essential in performing transportable experiments. In this poster, we will present a design of a two-dimensional grating magneto-optical trap (2D gMOT) requiring only a single input cooling beam. The cold atomic beam from the 2D gMOT will load atoms in a 3D gMOT implemented on an atom chip for efficient generation of BECs. This will lead to a robust, compact and efficient source of ultracold atoms that can be used in ground and space experiments.
