Final answer:
The half-value layer, kilovolts peak (kVp), and milliamperes (mA) are factors that impact the quality and quantity of the primary beam in X-ray production.
Step-by-step explanation:
Factors that will affect both the quality and quantity of the primary beam in an X-ray tube include the half-value layer, kilovolts (kV), and milliamperes (mA). The half-value layer impacts the beam's attenuation and is a measure of the material's ability to absorb X-ray photons, thereby influencing the quality. The kilovolts peak (kVp) setting influences the energy of the electrons accelerated towards the target and thus the energy of the resulting X-ray photons, directly affecting the quality and penetrating power of the X-ray beam. Lastly, the milliamperes setting controls the quantity of electrons produced by the cathode and hence, the number of X-ray photons generated, which determines the X-ray beam intensity or quantity.
