Research Accelerator Division

The superconducting portion of the SNS linear accelerator operates at 2 Kelvin (-455.8° F) and provides most of the acceleration of the ion beam.

The superconducting portion of the SNS linear accelerator operates at 2 Kelvin (-455.8° F) and provides most of the acceleration of the ion beam.

The Research Accelerator Division is responsible for operation of the Spallation Neutron Source (SNS) accelerator complex, which consists of a negative hydrogen-ion injector, a 1 GeV linear accelerator, a proton accumulator ring, and a liquid mercury target system. The main goal of the division is reliable delivery of beam power on target for neutron production.

The SNS accelerator is the only one of its kind in the world and provides the driving power to the SNS target system, where neutrons are produced. The accelerator systems are designed to provide 1.4 megawatts of proton beam power to the target and are currently operating at 1 megawatt. The accelerator system has been designed with the flexibility to provide additional scientific output in the future by increasing the beam power beyond 2 megawatts. (more about how SNS works)

The division is led by Director Kevin Jones.
