Beamline 7 Gets a MakeoverThe upgrades to Beamline 7 at the Stanford Synchrotron Radiation Laboratory (SSRL) are nearly complete, and will soon reward users with three state-of-the-art experimental stations illuminated by a modern insertion device and optics. BL7, which was one of the first hard x-ray insertion device beamlines in the world, has contributed important scientific results in the fields of macromolecular crystallography, materials scattering, and biological x-ray absorption spectroscopy. The $7.5 million upgrade was funded by the National Institutes of Health's National Center for Research Resources and by the Department of Energy's Basic Energy Sciences. In August 2005, SSRL staff began a complete makeover from the insertion device (the magnet in the SPEAR3 ring that generates x-rays for a particular beamline) all the way to the three end stations. Commissioning began on May 3 and test data will be taken before SPEAR3's current run ends in early August. Read a more technical description of the upgrade in SSRL Headline News. |

Ian Shipsey: Bringing Hearing to the DeafOn Monday, June 12, Purdue University's Dr. Ian Shipsey will present the colloquium "Bringing Hearing to the Deaf" at 4:15 p.m. in Panofsky Auditorium. In his talk, Shipsey will discuss the cochlear implant, the first device to successfully allow the profoundly deaf to regain some sense of hearing. A cochlear implant is a small electronic apparatus. Unlike a normal hearing aid, which amplifies sound, a cochlear implant is surgically implanted behind the ear where it converts sound waves into electrical impulses. These implants have instigated a popular but controversial revolution in the treatment of deafness, and they serve as a model for research in neuroscience and biomedical engineering. Shipsey will discuss the physiology of natural hearing from the perspective of a physicist. He will also touch on the function of cochlear implants in the context of historical treatments, electrical engineering, psychophysics, clinical evaluation of efficacy and personal experience. Finally, Shipsey will address the social implications of cochlear implantation and the future outlook for auditory prostheses. Learn more... |
