Question

Quizplus · Accepted Answer

Heat production is the primary factor that limits the size of the tungsten target, as the target has to be able to dissipate heat effectively to prevent damage and maintain performance. As the size of the target increases, so does the heat generated per unit area, which can lead to overheating and damage. The other choices are not the primary limiting factors for tungsten target size: A) cost can be a factor, but it is not the primary driver; C) and D) the limited kinetic energy of the electrons and photons affect the properties of the X-ray beam generated but do not limit the size of the target itself.
