Morphology

electron + beam

The meaning 'a focused stream of electrons' is directly and transparently derived from combining 'electron' (a charged particle) with 'beam' (a directed shaft or stream). Although it is a technical term, the noun-noun composition follows a regular, cross-linguistically common pattern, so a B1 learner who knows both constituents can reasonably infer the MWE meaning.

Etymology

Electron beam comes from the image of a beam of light but made of tiny electrons moving together in a narrow stream. That's why it means 'a focused stream of electrons' used in tools like electron microscopes or old TV tubes.
