A high resolution x-ray spectrometer utilizing Kirkpatrick-Baez optics and off-plane gratings

We present the design of a high resolution X-ray spectrometer for space based X-ray studies. This novel design utilizes a Kirkpatrick-Baez geometry with an off-plane grating as the secondary optic. This design has been proposed to NASA for flight onboard a suborbital rocket. The approach is low cost, low risk and has applications for future orbital missions.
