Ultracold atoms provide exciting opportunities for matterwave interferometry and tests of fundamental physics. When used as separate source chambers, Two-dimensional (2D) magneto-optical traps MOTs are advantageous in pre-cooling and faster loading of atoms to three-dimensional grating MOTs. To realise field applications of quantum sensors utilising cold atoms, there is need for simpler, more efficient and more compact sources.
In this poster, we will present the design, simulation and implementation of a 2D grating MOT requiring only a single input cooling beam. This will lead to a robust, compact and efficient source of ultracold atoms that can be used in field and space applications.
