Fermilab Develops Fast Detector for Dark Photon Search

4/7/2026

Summary

Story summary

Scientists at Fermi National Accelerator Laboratory (Fermilab) and partner institutions developed a detector to search for dark photons.
The detector uses flux tuning to adjust its frequency and capture weak signals efficiently.
The device can scan a frequency range 20 times faster than traditional methods.
In initial tests, it did not find dark photons.
Researchers plan to scale the technology by combining multiple cavities to cover a wider frequency range.
