X-Ray Optics
X-ray telescopes grazing incidence and diffractive optics materials science of thin films, coatings interferometry multiwavelength high angular resolution imaging.

X-Ray Sensors
Many future X-ray astronomy missions will need large focal plane arrays that are well matched to the optical performance of the X-ray telescope. These sensors should provide spatial, temporal, and spectral information at the highest resolution consistent with the mission science goals.
