When you gaze at the mighty Great Pyramid of Giza—sometimes called the Pyramid of Khufu—you’re looking at four and a half millennia of human effort. And in 2017, researchers revealed there’s more than ...

Muon radiography and tomography are innovative non‐destructive imaging techniques that employ cosmic-ray muons to probe the internal structures of large objects, from ancient monuments to active ...

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 ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics. Every minute, countless muons rain down from space, passing through ...
