Bremsstrahlung X-rays are produced when high-speed electrons are stopped by what?

Explanation:
Bremsstrahlung X-rays come from the deceleration of high-speed electrons as they pass through the electric field of nuclei in a solid target. In an X-ray tube, electrons are accelerated toward a metal target and, upon colliding with the nuclei, are suddenly slowed and deflected. This rapid change in velocity releases energy as X-ray photons, producing a continuous spectrum. It wouldn’t occur in a vacuum, isn’t produced by radioactive decay, and the key process here is deceleration in the target, not acceleration toward a nucleus.
