“…Therefore, the thickness of the required deposition depends on the angle of incidence of the X-rays [47]. The typical thickness of such depositions is more than ~10 Å [54], which is due to the complexity of coating smooth atomic structures, limiting their use only to soft X-rays (except at grazing incidence angle). The reflection at the boundary between the deposited interfaces obeys the Fresnel equations, where the amplitudes of the reflected and refracted waves correspond to the incident wave.…”

In this article, we present an overview of the application of X-ray self-emission methods for the imaging of hydrodynamic astrophysical phenomena in laboratory-scale experiments. Typical diagnostic approaches, their advantages, drawbacks, and application perspectives are considered. We show that X-ray imaging and spectroscopy methods with 2D and even 1D spatial resolution are valuable for numerous laboratory astrophysical problems. Furthermore, the methods revealed the hydrodynamic evolution, the spatial shape and structure, and spatial features of important parameters such as electron density and plasma temperature of astrophysical objects and related phenomena, which are also required for the verification of astrophysical models.

Silicon Pore Optics (SPO) was developed for light-weight X-ray telescopes with a large collecting area. Using technology from the semiconductor industry, thin mirror plates are produced from silicon wafers, and combined into modules. A large number of co-aligned modules forms the aperture. SPO enables ESA's next-generation flagship observatory NewAthena. In addition, it offers a large degree of customization. We discuss how SPO can be optimized for a mission by altering the properties of the plates and the configuration of the modules. This includes the membrane thickness and the spacing of the support-ribs of the plates. Multi-layer coatings optimize the effective area as a function of photon energy. A challenge is presented by the fixed height of the ribs, which is set by the thickness of the wafers from which the plates are made. For telescopes with a relatively short focal length, the fixed height leads to short mirror plates. Nevertheless, with a large number of modules, the total effective area may still be substantial. An avenue for future development could be to double the rib height. In addition to the properties of the mirror plates, the placement of the modules is customizable as well. For NewAthena, the modules are arranged in concentric rings, as an approximation of nested shells. On the other hand, the proposed NASA mission Arcus places its SPO modules in two sections ("petals"), which yield a substantially reduced cross-PSF. Therefore, the configurability of SPO makes it an attractive Xray optics technology for a wide range of applications.
