The Spallation Neutron Source at Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.
Higher power provides more neutrons for researchers who use the facility to study a wide range of materials, an ORNL press release said. The achievement marks a new operational milestone for neutron scattering in the United States and opens the door to studying significantly smaller materials with greater complexity, the press release said.
“The operation of SNS at 1.4 megawatts this cycle has been an outstanding achievement,” said Paul Langan, associate laboratory director for neutron sciences. “It reflects on the maturity of our facility and the high level of technical excellence of our engineering, operational, and scientific staff.”
The power increase was enabled by the combination of extensive improvements to the linear accelerator, including the recent replacement of the radio frequency quadrupole—the first accelerating structure of the accelerator’s frontend assembly, as well as improvements to the liquid mercury target.
