Morphology
The noun is a straightforward modifier–noun composition: 'control' (to regulate) + 'grid' (an electrode) yields a grid whose function is to regulate electron flow. This compositional pattern is productive and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the technical meaning.
Etymology
The noun control grid comes from early vacuum tubes, where a fine metal mesh sat between the hot metal that gave off electrons and the plate. The word grid is a metal net and control shows it acted like a gate that could stop or let the tiny particles called 'electrons' pass, so it controlled the tube's electric flow.
