15. The negative end of the x-ray tube is the: cathode.
16. The area of the envelope where x-rays should exit the tube is the: target window.
17. The anode serves as a(n): target for the electron interaction to produce x-ray,
electrical conductor, heat conductor.
18. The two types of anode designs are stationary and: rotating.
19. Tungsten is used to coat the anode disc because it: has a high atomic number.
