High spatial resolution of ultracold neutron (UCN) measurement is crucial to several experiments using ultracold neutrons, including UCN spectrometers, UCN polarimeters, quantum physics of UCNs, and quantum gravity. Here we describe experimental results to demonstrate sub-micron spatial resolutions for UCN position measurements obtained using a room-temperature CMOS sensor, extending our previous work [1] that demonstrated a position uncertainty of 1.5 microns. We also explore the use of machine learning and the open-source software Allpix Squared to automatically analyze the UCN position. The automated analysis for sub-micron position resolution in UCN detection combined with the fast data rates of current and next generation UCN sources will enable improved precision for all modern UCN studies.
