 the ion optical system is a microscope designed for imaging ultra-cold ground state and Ryberg atoms with magnification up to 1000 and spatial resolution of 100 nanometers, surpassing many standard techniques. It consists of four electrostatic lenses, a microchannel plate, and delay line detector, achieving single particle sensitivity with high temporal and spatial resolution. The design process includes ion optical simulations, aberration characterization, and resolution limit determination. Experimental realization in a cold atom setup is presented, and performance is investigated through patterned invitation with structure size down to 2.7 micrometers. The microscope meets the requirements for studying many body effects such as correlations in cold quantum gases and Ryberg molecule formation.
