摘要：

We report on the current status and performance of prototype hard X-ray optics we are producing for use on the High Energy Focusing Telescope (HEFT) experiment. The baseline substrates are thermally fanned glass mirrors that are overcoated with multilayers to provide good performance throughout the 20-80 keV bandpass. Progress made in the thermal forming process as well as in the multilayer performance has allowed production of optics that meet or exceed all HEFT requirements. We present metrology on the substrates and results from X-ray characterization. A novel mounting scheme for the individual telescope shells is currently being tested. If successful the mounting technique will produce a monolithic, extremely stiff and robust optic.
