Neutron Accelerator Sets World Record

The $1.4 billion Spallation Neutron Source facility, though still powering up, has established a new mark as the world's most powerful accelerator-based source of neutrons for scientific research.
The Oak Ridge National Laboratory announced Thursday that the SNS's neutron beam reached 183 kilowatts on Aug. 11, surpassing the 163-kilowatt record held by the ISIS facility at Rutherford Appleton Laboratory near Oxford, England.
Although the capacity of the ISIS facility is being doubled, Oak Ridge officials said their accelerator is designed to produce up to 10 times more neutrons than now.
Neutron scattering, discovered at Oak Ridge in the 1940s, is an important tool for studying how materials are made so that they can be improved upon -- lighter, cheaper, stronger.
