Collaboration: <strong>Search for Non-Interacting Particles Experiment (SNIPE) Collaboration</strong>

The Earth can act as a transducer for ultralight particles, such as hidden photons and axion-like particles, that are candidates for dark matter. The boundary conditions of the conductive Earth, non-conducting atmosphere, and conducting ionosphere can lead to these particles generating oscillating, coherent, global magnetic fields. The Search for Non-Interacting Particles Experiment (SNIPE) collaboration uses a network of magnetometers located in magnetically quiet environments to search for such signals. We present the results of the first science run, which led to improved terrestrial limits on the axion-like particle couplings and dark photon mixing parameter for frequencies in the range of 0.5 - 5 Hz. We also describe our efforts to expand the search range to higher frequencies in future searches.
