Part of an experiment involved measuring the intensity of an X-ray beam through a piece of aluminium as a function of emission current of the X-ray source. I originally fitted a linear fit to my data (although it does start to level off at high emission currents). The marker however said that it was not a linear fit, and said it was heading towards "saturation", but I am not quite sure what he meant. The detector is definitely NOT at saturation as the measured intensities are well below the saturation level (measured earlier)
Why does the intensity of the beam level off at high emission currents? Is it because there can only be so many electrons "boiled off" from the cathode, so it can only produce so many X-rays in collisions with the target?
