Effect of X-Ray tube Voltage on Short wavelength limit

Abstract

We studied the effect of the X-ray tube high voltage on short wavelength limit of continuum spectrum of x-ray tube . And confirm the Duane - Hunt relation and verify the inverse proportionality between the limit wavelength and tube high voltage and by gathering spectrum of x-ray at the voltage range of (15,20,25,30,35) kV, for the crystals NaCl, LiF then determine for all voltages, later determine Plank Constant experimentally.
