Generating x rays
WebThe energy of an x-ray beam may be described by identifying the peak operating voltage (in kVp). A dental x-ray machine operating at a peak voltage of 70,000 volts (70 kVp) for example, apples to a fluctuating voltage of as much as 70 kVp across the tube. This tube therefore produces x-ray photons with energies ranging to a maximum of 70,000 keV WebTo generate the electrons a coiled wire (a.ka. a filament) is heated until it gets hot enough that electrons boil off. The source of electrons is …
