Abstract

The University of Colorado maintains a grating evaluation facility to characterize optics from the far ultraviolet to the X-ray. The newest addition to this facility is a novel X-ray monochromator. Light is generated by a Manson electron impact X-ray source and passes through a monochromator which incorporates a grating in the off-plane mount at grazing incidence followed by an aluminum filter. From here, the light enters another vacuum chamber to illuminate the test grating, which disperses light onto a resistive anode MCP. This monochromator is characterized utilizing a variety of source anodes and voltages. Preliminary results from a high density test grating, also in the off-plane mount, display that this system is a highly effective tool for determining grating efficiencies.
