News Highlights
  • BigCal Shines On
    Lead glass bars in the BigCal detector in JLab's Experimental Hall C were damaged by radiation exposure, making them almost opaque. Researchers treated the bars with a portable UV light panel they designed and built. Upon removing the panel, they found the 1,744 bars "cured," their transparency restored. This ingenious process of curing the bars while still installed in the detector allowed the experiment to resume on schedule.
  • Hugh Montgomery Named JLab's New Director
    Hugh E. Montgomery, a highly regarded nuclear physicist with an extensive research portfolio and broad international experience, today was named director of the Department of Energy's Thomas Jefferson National Accelerator Facility.
  • Finishing Touches
    It's not often that major-league baseball and nuclear physics get to share the limelight, but that's what's happening at the Department of Energy's Jefferson Lab. The baseball connection involves a nine-cell niobium cavity developed by KEK accelerator scientists in Japan as one of several designs being tested for development for the proposed International Linear Collider. JLab is providing its superconducting radiofrequency expertise and specialized processing facilities.
  • Finding Tumors
    A medical imager built with the assistance of Jefferson Lab's Radiation Detector and Medical Imaging group has proven its mettle in initial tests. The tests demonstrated that the imager is capable of spotting tumors that are half the size of the smallest detected by standard imaging systems.
  • Saving Lives
    An Oregon woman says she is alive today because of the breast-imaging technology developed at Jefferson Lab. Sue Parham says the lab's technology made it possible for doctors to discover a slow-growing cancerous tumor that had gone undetected by mammograms.
  • Spin in the Neutron
    Physicists were in a whirl after measurements in the '80s revealed that the spins of the individual building blocks of the proton don't add up to the proton's actual spin. The so-called "proton spin crisis" spurred efforts to pin down where protons - and neutrons - get their spin. Pioneering measurements using the Proton Scintillator Array (shown here) in JLab's Hall A have opened the door for measuring some suspected sources of the neutron's spin.
