Morphology

linear + accelerator

The meaning is directly compositional: 'linear' (in a straight line) combined with 'accelerator' (a device that increases speed) clearly yields 'a device that accelerates along a straight path.' While the full technical details are specialized, a B1 learner who knows both constituents can infer the core meaning, and this compounding pattern is straightforward and cross-linguistically common.

Etymology

The name linear accelerator comes from how the machine works: linear means 'in a straight line' and an accelerator is something that 'makes faster'. It uses electric forces to speed tiny charged particles along that straight line, so the name tells you what the device does.
