Electron beam irradiators as seen by (fortunately well-shielded) GoPros:
https://www.youtube.com/watch?v=7H9SA8XCHug — 3.6 MeV and 7 mA of beam current.
https://www.youtube.com/watch?v=Uf4Ux4SlyT4 — 3.0 MeV and 50 mA of beam current.
For those that wonder... these beams are meant to kill even the toughest fungal spores. You have no chance make your time hahaha.
