A portable detector the size of a cookie box reveals in real time the cosmic particles that pass through your body every ...

In a muon tomography detector, cosmic-ray muons interact with an object and strike scintillators that emit photons. Wavelength-shifting fibers transmit the photons to photodetectors that digitize the ...

Researchers in the United States’ Fermilab moved the final subdetector for Mu2e into the ...

New research reports the most powerful cosmic rays ever detected. Because the rays lose energy as they travel through space, their detection at high energies means they are likely coming from sources ...
