This project entails the design, construction, interfacing, and testing of a computer-controlled target manipulator, a Ross-filtered diode array, and a soft X-ray grating monochromator for a laboratory-scale X-ray calibration system. The monochromator uses a variable line-spacing grating and the diode array uses different filters to isolate wavelengths within the soft X-ray region. The completed system will be used to calibrate future diagnostics for the National Ignition Facility which will explore the interaction of radiation at these wavelengths with various materials.
