What is required to move the electron stream rapidly across the x-ray tube?

Question

Quizplus · Accepted Answer

A high potential difference (also known as voltage) is required to accelerate the electrons in the electron stream, allowing them to move rapidly across the x-ray tube. This voltage is usually provided by a high voltage generator. While a magnetic field may be used to control the direction of the electron stream, it is not required to move the electrons rapidly. Focusing cups are used to focus the electron stream, but again, are not required for the movement of electrons. The copper mass in the target is related to the production of x-rays, but does not directly affect the movement of the electron stream.
