“…With the invention of Silicon Pore Optics [13,14], a solution to the challenge to meet the IXO optics technology requirements was found. The required stiffness is achieved due to the monolithic pore structure of the optic modules that are individually aligned into the optical bench, replacing the mounting approach for individual shells used in more traditional X-ray optic technologies [12,15,16].…”

“…In Figure 2, images A and B, the mounting concept for closed shells and sectors, respectively, is sketched. The Silicon Pore Optics relies on a different mounting concept [13,14,17,18]. The X-ray mirror elements are mounted along densely spaced lines, via ribs, which attach to the back of the mirror element; see Figure 2, image C. These mounting elements (ribs) have two functions: (1) they provide stiffness to the mirror element in the decisive longitudinal direction (parallel to the optical axis), and (2) they distribute the load over a line and not a point.…”

Silicon Pore Optics (SPO) is a new X-ray optics technology under development in Europe, forming the ESA baseline technology for the International X-ray Observatory candidate mission studied jointly by ESA, NASA, and JAXA. With its matrix-like structure, made of monocrystalline-bonded Silicon mirrors, it can achieve the required angular resolution and low mass density required for future large X-ray observatories. Glass-based Micro Pore Optics (MPO) achieve modest angular resolution compared to SPO, but are even lighter and have achieved sufficient maturity level to be accepted as the X-ray optic technology for instruments on board the Bepi-Colombo mission, due to visit the planet Mercury. Opportunities for technology transfer to ground-based applications include material science, security and scanning equipment, and medical diagnostics. Pore X-ray optics combine high performance with modularity and economic industrial production processes, ensuring cost effective implementation.

“…It allows wide field imaging of a 30' FOV area on the sky with an effective area > 1500 cm 2 at 1 keV and > 150 cm 2 at 6 keV. The detector has three different sections including an inner array of 26 x 26 pixels with energy resolution of 2.5 eV, an outer array of 72 x 72 pixels with energy resolution < 5 eV, and a third array 20 x 20 pixels located at on one side of the outer array for detecting GRBs.…”

“…In particular, the optics development will rely partially on the Silicon Pore Optics (SPO) technology under development for IXO [2][3] and partially on the Ni electroforming optics technology already proven in several X-ray telescopes [4][5][6] [7]. The instrument design has been optimized to give a high grasp (the effective area on-axis times the solid angle of the field of view) by having a short focal length (2.5 m).…”

The mirror module design for the cryogenic x-ray imaging spectrometer on-board ORIGIN

ORIGIN is a medium size high-energy mission concept submitted to ESA in response to the Cosmic Vision call issued on July 2010. The mission will investigate the evolution of the Universe by performing soft X-ray high resolution spectroscopic measurements of metals formed in different astrophysical environments, from the first population III stars at z > 7 to the present large scale structures. The main instrument on-board ORIGIN will be a large format array of TES X-ray micro-calorimeters covering a FOV of 30' at the focal plane of a grazing incidence optical module with a focal length of 2.5 m and an angular resolution of 30'' HEW at 1 keV. We present the optical module design which is based on hybrid technologies, namely Silicon Pore Optics for the outer section and Ni electro-forming for the inner section, and we present the expected performances based on test measurements and ray-tracing simulations.

“…SPO were invented in 2002 [1,2] to enable future x-ray observatories that would succeed the then newly launched CHANDRA [3] and XMMNewton [4] telescopes. The technology development progressed over the years from a proof of concept stage to a very mature x-ray optic that now forms the basis of the Advanced Telescope for High Energy Astrophysics (ATHENA), the second (L2) large class mission with the ESA Cosmic Vision Program [5], selected in June 2014.…”

The ATHENA mission, a European large (L) class X-ray observatory to be launched in 2028, will essentially consist of an X-ray lens and two focal plane instruments. The lens, based on a Wolter-I type double reflection grazing incidence angle design, will be very large (~ 3 m in diameter) to meet the science requirements of large effective area (1-2 m 2 at a few keV) at a focal length of 12 m. To meet the high angular resolution (5 arc seconds) requirement the X-ray lens will also need to be very accurate. Silicon Pore Optics (SPO) technology has been invented to enable building such a lens and thus enabling the ATHENA mission. We will report in this paper on the latest status of the development, including details of X-ray test campaigns.
