Ion implantation for figure correction of high-resolution x-ray telescope mirrors
… for future high-resolution, large-aperture x-ray telescopes continues to challenge the x-ray astronomy instrumentation community. Building a large-aperture telescope requires thin, lightweight mirrors; due to the very low stiffness of thin mirrors, these are difficult to fabricate, coat, and …

Design and modeling of a third generation slumping tool for X-ray telescope mirrors/
… 5 arcsec are in demand for the International X-Ray Observatory. Several glass flattening techniques are presented in this thesis, including a method of thermally shaping individual sheets of glass using porous mandrels as air bearings developed at the Space Nanotechnology Lab. This method, a …

The Design and Analysis of Several Configurations for a Two Channel, Three Mirror X-Ray Telescope.
In 1922, Compton [2] first reported reflecting x-rays from polished surfaces of glass and other materials. The angles of incidence required were very large—in the case of glass, 89 degrees 49 minutes of arc—for reflection of x-rays of 1.27Ã… wavelength. Such reflection of x-rays is called …

Metrology and mechanics for manufacturing space-based x-ray grating spectrometers
… optical systems in many fields - including telescope, microscopy, lithography, and display technologies. A space x-ray telescope needs more stringent requirements as it observes distant space objects using a limited number of x-ray photons in a harsh space environment. The optical …

Imaging X-ray spectroscopy with micro-X and Chandra
High spectral resolution observations of X-ray phenomena have the potential to uncover new physics. Currently, only point sources can be probed with high resolution spectra, using gratings. Extended objects like supernova remnants cannot be dispersed, leaving the dense forest of emission lines …

High-resolution studies of charge exchange in supernova remnants with Magellan, XMM-Newton, and Micro-X
… in two energy bands: the optical and the X-ray. The optical study, performed using both imaging and high resolution spectroscopy from the IMACS instrument on the Magellan Baade Telescope at Las Campanas Observatory, seeks to identify 'Balmer-dominated shocks' in the remnant, which signal the …

Accretion flows and neutron star heating in low-mass X-ray binaries
X-ray binaries are excellent test beds for studies of high-energy accretion flows and the properties of compact objects. Neutron star (NS) low-mass X-ray binaries (LMXBs) vary in brightness by almost 8 orders of magnitude and are hosts to diverse accretion flows, transporting varying amounts of …

Optimizing The Performance Of As-manufactured Grazing Incidence X-ray Telescopes Using Mosaic Detector Arrays
The field of X-ray astronomy is only forty (43) years old, and grazing incidence X-ray telescopes have only been conceived and designed for a little over fifty (50) years. The Wolter Type I design is particularly well suited for stellar astronomical telescopes (very small field-of-view). The first …
