Abstract

We are developing Wolter-I X-ray optics for use in SmallSat missions. These optics are being designed for telescope focal lengths on the order of 0.5 - 1 m, much shorter than typical Astrophysics missions. The various parameters of the optics module: diameter, length, number nested shells, coatings, etc., depend partly on the spacecraft bus but the final design is driven by the science and instrument requirements of the mission (effective area, resolution, and energy band of interest). Ray trace software was developed and used to project the performance of several optics configurations, which, designed for SmallSat missions, meet the instrument requirements for the SmallSat Exosphere Explorer of hot Jupiters (SEEJ) . Results of this modeling is presented.
