"Breakthrough Experiment Achieves Unprecedented Sensitivity in Dark Photon Detection"
Scientists at Fermilab's Dark SRF experiment have achieved unprecedented sensitivity in their search for dark photons, theorized particles that could explain the existence of dark matter. By using superconducting radio frequency (SRF) cavities to trap and detect the transition of ordinary photons into dark photons, the experiment has set the world's best constraint on the existence of dark photons in a specific mass range. The innovative use of SRF cavities, typically used in particle accelerators, has allowed for greater sensitivity and opens up new possibilities for future experiments in the field of particle physics.
