Watching ionization in a new light

Nature Photonics volume 20, pages 609–610 (2026) Cite this article

Ultrashort MeV electron pulses are found to induce a surprisingly strong modulation in the optical transmission of common semiconductors, enabling room-temperature detection of ionizing radiation with sub-10-ps timing precision. The findings could lead to next-generation medical imaging and radiation diagnostics.
