    Abstract: An x-ray fluorescence technique for detecting the level of arsenic in a sample of water or body fluid. Arsenic and lead are expected to fluoresce in a first energy band and lead is expected to also fluoresce separately in a second energy band. An excitation path directs x-rays toward the sample; a first detection path detects x-ray fluorescence of the first energy band from the sample; and a second detection path detects x-ray fluorescence of the second energy band from the sample. The level of arsenic can be obtained by analyzing the x-ray fluorescence from both detection paths, and using a constant which relates the level of lead in the second energy band to the level of lead in the first energy band. The excitation path and each detection path may each include a monochromating optic to transmit the desired x-ray energy band, e.g., a doubly curved optic.

    Abstract: A diffractor for electromagnetic radiation is based on a pseudo-spherical stepped geometry designed under the constant step width conditions. The diffractor consists of a few small pseudo-spherical curved dispersive elements (oriented crystal surfaces or gratings) that are located on a focal circle. The location on the focal circle of each element is made to guarantee the same Bragg angle for the incident radiation. Thus a diffractor is an array of diffracting elements (nullstepsnull), each one contributing to the total solid angle of the diffractor, that increase the spectral output of the device without decreasing the resolution. Scheme and parameters of different devices based on the analysis of x-rays secondary are described.
