DAMPE Satellite Reveals Cosmic Rays Share Spectral Break Near 15 Teravolts
The Dark Matter Particle Explorer (DAMPE) satellite has identified a universal spectral softening in the energy spectra of primary cosmic‑ray nuclei—including protons, helium, carbon, oxygen and iron—around a rigidity of 15 teravolts. Published in Nature, the finding shows the particle count drops more sharply beyond this point, a pattern consistent across all studied elements. The result strongly favors rigidity‑dependent acceleration and transport models while ruling out energy‑per‑nucleon explanations with 99.999% confidence. DAMPE’s AI‑enhanced detectors and the Swiss‑Chinese collaboration were pivotal to the breakthrough.
