TL;DR: The High Energy Transmission Grating (HETG) has been used at the Chandra X-Ray Observatory (Chandra X-ray Observatory) for 5 years of flight experience as discussed by the authors.

TL;DR: The High Energy Transmission Grating (HETG) has been used at the Chandra X-ray Observatory for five years of flight experience as discussed by the authors, and has been successfully used for ground testing and calibration.

TL;DR: In this paper, the authors propose a contract with the U.S. National Aeronautics and Space Administration (Nasa) for the development of a satellite communications system.

TL;DR: In this article, the angular spectrum representation of the reflection of a beam of light at a plane interface is treated using angular spectrum representations, and the Goos-Hanchen shift is found to be proportional to the first derivative of the phase of the reflectance, which gives rise to a shift of the reflected beam along its direction of propagation.

TL;DR: A deep-UV Shack-Hartmann surface mapping tool has been created to determine whether the foils meet these manufacturing requirements and to provide active metrological feedback during the assembly procedure, and to develop a device that makes progress towards actual flight module assembly.
