The neutron scattering facility and user program at the Oak
Ridge National Laboratory' High Flux Isotope Reactor (HFIR) are undergoing major
overhauls. Recently, a reactor upgrade project was completed during which bigger
beam tubes were installed in the reactor. A new cold-source and cold instrument
guide hall are currently under construction as part of this project and will
include two world class SANS machines one of which will be dedicated to
biological studies. The first of the upgraded thermal beam instruments (three
triple-axis spectrometers) are back in place. Each of these three instruments
exhibit higher neutron flux as a result the upgrades. They also feature all new
LabView instrument control and data acquisition systems. The next year will see
a new instrument being installed every few months. In addition to the facility
and hardware upgrades, the HFIR Center for Neutron Scattering has instituted a
formal user program. Calls for proposals will be issued on a regular schedule
for the neutron scattering instruments in the user program. At the heart of the
user program is an external, peer-reviewed, proposal system for determining beam
time allocations. The three triple axis spectrometers are already available for
users and other instruments will be included as they are installed.
