ESA’s New X-ray Optics To Observe The Hot Universe
2014-05-16 03:41:51

ESA A new idea to use super-polished silicon wafers as the heart of a telescope is set to reveal more of the hot, high-energy Universe, peering back into its turbulent history. Invisible X-rays tell us about the very hot matter in the Universe – black holes, supernovas and superheated gas clouds. Today’s X-ray observatories, ESA’s XMM-Newton and NASA’s Chandra, were launched in the last century, and are still delivering world-class science. But they are starting to age. To...

Newly Developed Holographic Process Uses Image-stabilized X-ray Camera
2014-01-07 11:40:04

Helmholtz-Zentrum Berlin A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focusing optics being firmly fixed to the object to be imaged. While this approach initially provides a blurry image, this can be focused in the computer based on the hologram information. At the same time, the rigid connection between the object and the...

World's Sharpest X-ray Beam Shines At DESY
2013-09-30 11:42:20

Deutsches Elektronen-Synchrotron DESY The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometers – this is ten thousand times thinner than a human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt from the Institute of X-ray Physics and of Professor Hans-Ulrich Krebs from the Institute of Materials Physics of the...

As elements of the integrated circuits running our computers, phones and electronics, silicon wafers are everywhere. An ESA-led effort is establishing an out-of-this-world use for these commonplace items: when stacked together precisely by the thousand they promise to deliver astronomy's clearest X-ray view yet of the most violent regions of space. "ESA has been working with specialist European firms to develop this new optical technique and build up a supporting industry," said Marcos...

Not only were images of test patterns (lines formed by layers of chromium and silicon in cross-section) sharper than those made with the XM-1's current 25-nanometer-resolution MZP, the new MZP was able to obtain sharp images of lines a mere 15 nanometers apart "” where the older zone plate had seen only a featureless field of gray. "Nanoscience and nanotechnology are everywhere around us "” biology and chemistry are nanoscience by nature "” but we need better analytical...
