Which of the following is part of the x-ray tube anode?

The anode in an x-ray tube is primarily made up of the positive electrode and the target. The positive electrode, also known as the anode, is where the electrons generated at the cathode are directed. When these high-energy electrons strike the target material, usually made of tungsten, x-rays are produced. The target is critical because it is the surface where the interaction between the electrons and the atoms occurs, resulting in the emission of x-rays.

By including both components— the positive electrode and the target—this answer accurately reflects the dual role of the anode in the x-ray tube's functioning. The anode not only provides a positive charge to attract electrons from the cathode but also serves as the actual target for the electrons to produce x-rays. Therefore, recognizing that both the positive electrode and the target are integral parts of the anode clarifies their essential functions in the x-ray generation process.
