Which statements about a conventional X-ray tube are correct?

Select all that apply

• Option A

  Increasing the accelerating voltage can decrease the cutoff wavelength of the continuous spectrum

• Option B

  Increasing filament heating generally increases X-ray intensity by increasing thermionic emission

• Option C

  Increasing filament heating alone necessarily increases the maximum X-ray photon energy

• Option D

  The continuous X-ray spectrum is produced mainly by rapid deceleration of energetic electrons in the target
