Morphology
The noun–noun compound directly combines 'ion' (charged atom/molecule) with 'beam' (a directed shaft or stream), so a learner who knows both words can infer 'a directed stream of ions'. The formation is compositional and follows a common, cross-linguistic pattern for technical compounds, so the meaning is transparent despite being a technical term.
Etymology
The noun ion beam comes from the words ion, a charged atom, and beam, a narrow stream like light from a flashlight. Imagine many charged atoms moving together in a tight, fast line like a beam of light, so an ion beam is a focused stream of charged particles used in experiments and to change materials.
