To prevent getting exposed to x-rays while working with an x-tube, it is typically enclosed by lead. The main motivation for using lead is that it is a high-Z material that is an excellent absorber of x-rays (higher Z mtrl -> better absorber). In addition, using thicker lead is more effective than using thinner lead, simply because more x-rays are absorbed by the thicker one than a thinner one. 1. What charge is needed to focus the electrons that are aimed at the target?
A. Positive
B. Negative
C. Neutral
D. Alternating
Answer:B
