For members: Construction planned for SNS power upgrade

Posted at 12:21 pm July 19, 2019

The Spallation Neutron Source at Oak Ridge National Laboratory reached its operational power design level by running a neutron production cycle at 1.4 megawatts, the lab said Tuesday, Nov. 27, 2018. (Photo courtesy ORNL)

 

Construction is planned in December for a project to upgrade proton power at the Spallation Neutron Source at Oak Ridge National Laboratory.

The construction could last about one year, and it will be limited to the buildout of what is known as the klystron gallery, ORNL said in June. The klystron gallery houses the radio-frequency systems that power the structures used to accelerate a negatively-charged hydrogen ion beam in the linear accelerator at SNS.

SNS generates neutrons for scientific research by propelling protons down a linear accelerator. When the protons collide with a liquid mercury target, they create a “spall” of neutrons that are sent down beam lines surrounded by research instruments.

The proton power upgrade will eventually double the power of the SNS proton beam from 1.4 megawatts to 2.8 megawatts. The current total estimated project cost is $245 million.
