X-ray fluorescence from thin foils inserted into the NPS linac have been used to measure the the integrated electron beam current only. The measured x-ray flux and the known inner shell ionization cross sections are used to obtain measurements of dark currents of the order of ten to the minus fourteenth amperes. The same arrangement allows continuous, in-situ energy calibration of our Si(Li) detector in the electromagnetic noise environment of the linac. This technique was originally developed to perform absolute production efficiency measurements of parametric x-ray generation in the 5-60 KeV range
