The Transient High Energy Sources and Early Universe Surveyor is an ESA M5 candidate mission currently in Phase A, with Launch in $\sim$2032. The aim of the mission is to complete a Gamma Ray Burst survey and monitor transient X-ray events. The Unive

Space Telescopes and Instrumentation 2018: Ultraviolet to Gamma Ray.
We report on the design, development and measured performance of the Microchannel plate X-ray optics for the Mercury imaging X-ray spectrometer instrument, due to fly to Mercury on the ESA/JAXA BepiColombo mission in 2018. This paper serves as a prog

In support of future x-ray telescopes ESA is developing new optics for the x-ray regime. To date, mass and volume have made x-ray imaging technology prohibitive to planetary remote sensing imaging missions. And although highly successful, the mirror

We identify all the significant aberrations that limit the performance of square pore micro-channel plate optics (MPOs) used as an X-ray lobster eye. These include aberrations intrinsic to the geometry, intrinsic errors associated with the slumping p

Modern microchannel plate detectors exhibit low quantum efficiency in the extreme ultra violet range compared to those manufactured before 1990. The cause of this reduction in efficiency is unknown. We describe recent investigations into the along-ch

Square-pore microchannel plate (MCP) X-ray optics of the “lobster-eye” geometry have frequently been described in the literature. We have now investigated the use of a radial channel packing geometry which, in the context of an MCP pair slumped t

We investigate, by ray-trace simulation, two hard X-ray telescopes based on microchannel plate (MCP) optics. The first is the, by now well known, lobster-eye geometry, while the second is a novel design. The second design uses a pair of MCPs with squ

The Mercury Imaging X-ray Spectrometer (MIXS) on the BepiColombo Mercury Planetary Orbiter (MPO), will measure fluorescent X-ray emission from the surface of Mercury in the energy range 0.5 – 7.5 keV, which is induced by incident solar X-rays and s
