What is the x-ray tube?

The essential idea is that an x-ray tube is a vacuum-sealed device where electrons are emitted from a heated filament and accelerated toward a metal target. When these fast electrons strike the target, their kinetic energy is converted into x-ray photons. The vacuum envelope is crucial because it allows smooth electron flow without collisions with air molecules and prevents arcing, enabling efficient x-ray production. Other features like shielding or cooling support operation, but the core function is the conversion of electron energy into photons inside a vacuum tube.
