The Cold Triple Axis spectrometer, a new addition to Oak Ridge National Laboratory's High Flux Isotope Reactor and a complementary tool to other neutron scattering instruments at ORNL, has entered its commissioning phase. The CTAX uses "cold" neutrons from the HFIR cold source to study low-energy magnetic excitations in materials. Cold neutrons are slower than their "thermal" neutron counterparts, and thus perfect for probing low-energy dynamics. The instrument, which moves by way of air pads...

Findings released at the annual Goldschmidt Conference at the University of Tennessee, Knoxville New intense sources of radiation at national facilities in Chicago, New York, and Tennessee coupled with the next generation of sensitive detectors are allowing geochemists like John Parise to gather images and data on minerals in one second that would take years of equivalent exposure on conventional laboratory x-ray facilities. John Parise, professor, mineralogist and solid-state chemist at...

Unless you're interested in isotopic labeling, neutrons don't figure much into chemistry. Neutral in charge and a bit bigger than a proton, the neutron neither gives an atom its name nor determines much about its reactivity. But neutrons have some unsung properties that make them useful for investigating matter. Because they are neutral, they can penetrate deeper into a sample than electrons can. Because they have mass and spin, they have a magnetic moment and can probe magnetism. Because...

Neutron scattering experiments performed at the Department of Energy's Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material's magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors. The work, published in a recent Nature Physics, was performed at ORNL's Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR) along with the ISIS...

European researchers obtain access to world's strongest neutron source A unique large-scale research device from Jlich went into operation in the USA yesterday. At the strongest neutron source in the world, the spallation source SNS in Oak Ridge, Tennessee, Forschungszentrum Jlich inaugurated a so-called neutron spin echo (NSE) spectrometer. The NSE spectrometer enables detailed observations to be made of the motion of proteins and polymers. It will thus help to develop improved plastics or...

A major milestone has been achieved in the completion of the UK's next-generation particle accelerator, ALICE, which is set to produce an intense beam of light that will revolutionize the way in which accelerator based light source research facilities will be designed in the future. To mark the occasion, ALICE was visited today, 13 November 2008, by His Royal Highness The Duke of Kent as part of his visit to the Daresbury Science and Innovation Campus. ALICE is based at the Science and...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
