International Electron Beam Day 2026

Today, April 30th, we celebrate International Electron Beam Day – a global recognition of electron beam technology and the dedicated professionals who advance it.

International Electron Beam Day commemorates April 30, 1897, when physicist J.J. Thomson first proposed the existence of the electron, a discovery that revolutionized physics and paved the way for transformative technologies. More than a century later, electron beam technology has become essential to modern industry, sterilizing medical devices, strengthening materials, improving food safety, and enabling advanced manufacturing.

The iia, in partnership with E-BEAM Services, is proud to support this celebration of the scientists, engineers, operators, and innovators who make electron beam technology possible.

Celebrate with us today:
