The experiment will measure the thickness of a thin aluminum foil by sending a beam of x-rays through the foil. The thickness of the foil is related to the difference in the intensity of x-rays that pass through the aluminum window and the initial intensity of the x-ray source. The intensity is also related to a property of the material known as its attenuation coefficient. To calculate the attenuation coefficient, another foil with known thickness, mass, and surface density is used to calculate the attenuation coefficient.
