X-ray telescopesx-ray astronomyadjustable opticsHigh-energy astrophysics is a relatively young scientific field, made possible by space-borne telescopes. During thehalf-century histoy of x-ray astronomy, the sensitivity of focusing x-ray telescopes-through finer angular resolutionand increased effective...
Here we demonstrate ultralong-lived X-ray trapping for flat-panel-free, high-resolution, three-dimensional imaging using a series of solution-processable, lanthanide-doped nanoscintillators. Corroborated by quantum mechanical simulations of defect formation and electronic structures, our experimental ...
The book presents a detailed description of high-resolution x-ray scattering methods suitable for the investigation of the real structure of single-crystalline layers and multilayers, including structure defects in the layers and at the interfaces. Particular attention is devoted to lateral structures in...
Owing to its unique penetrating power and high-resolution capability, X-ray imaging has been an irreplaceable tool since its discovery. Despite the significance, the resolution of X-ray imaging has largely been limited by the technical difficulties on X-ray lens making. Various lensless imaging me...
Supernova Remnants:X-Ray SpectraWe review results obtained with the Focal Plane Crystal Spectrometer (FPCS) on the Einstein Observatory. Clear evidence is found for departures from ionization equilibrium in the interior of Puppis A. This comes from the observed weakness of the forbidden lines ...
High-resolution X-ray Computed Tomography (HRXCT) or micro-CT (mu CT) is a frequently used non-destructive 3D imaging and analysis technique for the investigation of internal structures of a large variety of objects, including geomaterials. Although the possibilities of X-ray micro-CT are becomi...
(b) Schematic of the optical system used to focus the X-ray beam (17.5 keV) down to the range of 100 nm. This coherent focusing scheme is required for high resolution to detect a thinned BLM, while plane wave illumination can only detect the signal of BLMs which are swollen w...
Superconducting tunnel junctions coupled to superconducting absorbers may be used as high-resolution, high-efficiency X-ray spectrometers. We have tested devices with niobium X-ray absorbing layers coupled to aluminum layers that serve as quasiparticle traps. In this work we measure the current pulses...
High Resolution 3D X-ray Microscope is a non-destructive method employed with an optical microscope to enhance the magnification, which uses 2D X-ray tomography to take sample images at all angles while turning the fixed sample 360 degrees. Physical images of the tested object are then constructe...
