Increasing the kVp serves to increase the quantity of what?

Increasing the kilovolt peak (kVp) primarily influences the quality and quantity of X-ray photons produced during the imaging process. When the kVp is raised, the voltage difference in the X-ray tube increases, which accelerates the electrons from the cathode to the anode with greater energy.

This increase in energy results in a higher intensity of X-ray photons emitted when the accelerated electrons strike the target material in the anode. As a result, increasing kVp not only enhances the penetrative power of the produced X-ray photons but also leads to a greater quantity of these photons generated.

While electrons are indeed impacted (in terms of their energy) by the increase in kVp, the question specifically pertains to the quantity of photons produced, which makes the correct answer focused on X-ray photons. Other particles mentioned, such as neutrons and protons, are not involved in the X-ray generation process and therefore are not relevant to this question.
