Abstract: This talk explores the research trajectory of the SNIPE Hunt collaboration, initially focused on detecting ULDM axions or dark photons converting into magnetic fields within the space between the ground and the ionosphere, which together act as a 10,000 km-scale cavity. Recent efforts include a novel technique to expand the mass range accessible by the detector, by leveraging the unique space-dependence of DM-induced magnetic fields. I will also discuss ongoing research into utilising km-scale cavities, which are not only surprisingly practical to build, but could also provide sensitivities comparable to other much more resource-intensive experiments, for a fraction of the price.
