The manufacturing of semiconductor wafers used in all types of electronics involves etching small features onto a wafer with lasers, a process that is ultimately limited by the wavelength of the light itself. The semiconductor industry is rapidly approaching this fundamental limit for increasing the speed of the microchip. The development of a new intense 13.5-nm (extreme ultraviolet or EUV) light source will resolve this issue by reducing the feature size by an order of magnitude or so,...

Air Force Office of Scientific Research-supported physicists at the University of California, Berkeley in collaboration with researchers from the Max Planck Institute of Quantum Optics and the U.S. Department of Energy's Lawrence Berkeley National Laboratory, became the first researchers to observe the motion of an atom's valence or outermost electrons in real-time by investigating the ejection of an electron from an atom by an intense laser pulse. In the experiments, an electron in a krypton...

For almost 15 years, the EIT camera on board SOHO transmitted a picture of the solar corona every 12 minutes, providing ground-breaking observations of the Sun that changed our perception and understanding of our star. After a remarkable career, this instrument has now eased into semi-retirement. Although no longer as active as during its heyday, EIT will still provide snapshots of the Sun - at a more leisurely pace. Launched in late 1995 and still in operation, the SOHO mission has...

An international team of scientists led by groups from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, and from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley has used ultrashort flashes of laser light to directly observe the movement of an atom's outer electrons for the first time. Through a process called attosecond absorption spectroscopy, researchers were able to time the oscillations between...

Our world is full of integrated semiconductor circuits, commonly known as microchips. Today you find them in computers, cars, mobile phones and in almost every electrical device. Technology from ESA's XMM-Newton space telescope will make these chips much smaller, faster and cheaper. The circuits are etched into today's microchips by ultraviolet light. The demand for faster and more powerful chips requires the use of extreme ultraviolet (EUV). Much smaller semiconductor circuits can be...

Every 11 years, the sun undergoes a furious upheaval. Dark sunspots burst forth from beneath the sun's surface. Explosions as powerful as a billion atomic bombs spark intense flares of high-energy radiation. Clouds of gas big enough to swallow planets break away from the sun and billow into space. It's a flamboyant display of stellar power. So why can't we see any of it? Almost none of the drama of Solar Maximum is visible to the human eye. Look at the sun in the noontime sky...

Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own. Sodium-like tungsten ions could pepper"”and conveniently monitor"”the hot plasma soup inside fusion energy devices, potential sources of abundant, clean power. Tungsten"”having the highest melting point of any...

Researchers are adapting the same methods used in fusion-energy research to create extremely thin plasma beams for a new class of "nanolithography" required to make future computer chips.Current technology uses ultraviolet light to create the fine features in computer chips in a process called photolithography, which involves projecting the image of a mask onto a light-sensitive material, then chemically etching the resulting pattern.New nanolithography will be needed to continue advances in...
