Athena, the largest space-based x-ray telescope to be flown by European Space Agency, uses a revolutionary new modular technology assemble its 2.6 m diameter lens. The lens will consist of several hundreds smaller lenslets, called mirror modules, which each about 70 pairs. Those modules are arranged in circles large optics structure and focus photons with an energy 0.5 10 keV at distance 12 onto detectors Athena. point-spread function (PSF) optic shall achieve half-energy width (HEW) 5" 1...

Silicon Pore Optics is the X-ray mirror technology selected for European Space Agency's Athena observatory. We describe testing and characterization cycle that optics are subjected to at PTB's Pencil/Paraller Beam Facility (XPBF) 1 2 beamlines synchrotron radiation facility BESSY II. Individual stacks measured with a pencil beam determine their optical quality orientation of axis. Using metrics based on manufacturing metrology, then paired in primary-secondary Wolter-I-like systems, turn...

The mirror modules composing Athena's X-ray optics are made with the Silicon Pore Optics (SPO) technology. SPO is produced as stacks of 38 plates, which paired to form Units (XOUs) following a modified Wolter I geometry. In current design, module composed two confocal XOUs glued in between pair brackets that freeze configuration and provide interfaces structure. Mirror assembled at XPBF2 beamline PTB synchrotron radiation facility BESSY II, using dedicated jigs. this paper we present latest...
Silicon Pore Optics (SPO) have been invented and developed to enable x-ray optics for space applications that require a combination of high angular resolution while being light-weight allow achieving large mirror surface area. In 2005, the SPO technology development was initiated by European Space Agency (ESA) flagship telescope mission is currently planned as baseline NewATHENA scheduled launch in 2030s. Its more than 2m diameter will be segmented comprises 492 individual grazing-angle...
The Silicon Pore Optics (SPO) technology has been established as a new type of X-ray optics and will enable future observatories such Athena Arcus. SPO is being developed at cosine Research B.V. together with the European Space Agency (ESA) academic well industrial partners. For Athena, about 150,000 mirror plates are required. With spin-in from semiconductor industry, mass production processes can be employed to manufacture rectangular in high quality, large quantity low cost. Over last...
The European Space Agency (ESA), cosine and its partners have been developing for 20 years the Silicon Pore Optics (SPO) technology. SPO enables next generation of space x-ray telescopes, with increased sensitivity resolution. NewAthena, New Advanced Telescope High Energy Astrophysics, has just endorsed by ESA as one Lclass mission, to launch around 2037. NewAthena's optic is modular consists up 600 mirror modules that form together a ~2.5 m diameter X-ray focal length 12 an angular...
The European Space Agency (ESA) is developing the Athena (Advanced Telescope for High ENergy Astrophysics) X-ray telescope, an L-class mission in their current Cosmic Vision cycle long-term planning of space science missions. Silicon Pore Optics (SPO) are a new type optics enabling future observatories such as and being developed at cosine with ESA well academic industrial partners. These high-performance, modular, lightweight yet stiff, high-resolution shall allow missions to reach...
We present a frequency-shifted feedback (FSF) laser based on tapered amplifier. The operates as coherent broadband source with up to 370GHz spectral width and 2.3us coherence time.
