Work starts to increase power of SNS proton beam

Construction work has started on a part of a project to double the power of the proton beam in the Spallation Neutron Source at Oak Ridge National Laboratory.

It’s the first construction work at the $1.4 billion SNS since 2006.

The current work is limited to what is known as the klystron gallery. It houses radio-frequency systems. They power the structures that are used to accelerate a negatively-charged hydrogen ion beam in the linear accelerator at SNS.

ORNL has previously said the klystron gallery construction could last about one year.

The work is part of a project called the proton power upgrade, or PPU. It will eventually double the power of the SNS proton beam from 1.4 megawatts to 2.8 megawatts. That could be a seven-year project. The potential cost has previously been estimated at $245 million.

Next major decision anticipated for second target station at SNS

More than 200 scientists from around the world met from Oct. 27 to 29, 2015, at the U.S. Department of Energy’s Oak Ridge National Laboratory to provide input on the scientific instruments that would be installed at a proposed Second Target Station, or STS, pictured above at center right at the Spallation Neutron Source.

The next decision about the second target station at the Spallation Neutron Source could be made later this year or in the first quarter of next year, U.S. Energy Secretary Dan Brouillette told a House subcommittee on Thursday. The next decision would include an alternative selection and a cost range.

The $1.4 billion SNS is located on Chestnut Ridge at Oak Ridge National Laboratory. It provides neutrons for research.

The second target station has been part of SNS plans for many years. It’s one of two upgrades being pursued at SNS. The other is a proton power upgrade, which is expected to double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts.

The second target station has a current estimated cost range of $800 million to $1.5 billion. The U.S. Department of Energy said the second target is needed more than a decade ago, in January 2009. The second target station would use a narrow proton beam and a compact, rotating, water-cooled tungsten target. It is expected to fill gaps in materials research that require the combined use of intense, cold (longer wavelength) neutrons and instruments that can help analyze complex materials. It could have up to 22 experimental beamlines.

For members: Construction planned for SNS power upgrade

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.

ORNL pursuing two major upgrades at SNS

  Note: This story was updated at 10:15 a.m. Aug. 1. Oak Ridge National Laboratory is pursuing two major upgrades to its Spallation Neutron Source that would allow new scientific research and could cost more than $1 billion. The two proposed upgrades are a proton power upgrade and a second target station. The two projects are in different stages of review at the U.S. Department of Energy, ORNL spokesperson Morgan McCorkle said. The proton power upgrade, or PPU, is being pursued first, and its current cost estimate is a little more than $200 million, McCorkle said. If approved, it would double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts. The upgrade would allow new types of research at SNS, and it would increase the number of scientists who can use the facility each year, McCorkle said. “The PPU will enable experiments that are not currently feasible, such as experiments on smaller or less concentrated samples, and experiments under more extreme environmental conditions,” McCorkle said. “The new scientific capabilities will support research in areas such as soft matter, quantum materials, chemistry, functional materials, and biology. Some examples of everyday products that may be improved by these discoveries include cell phones, batteries, computers, building materials, and drugs.” The proton power upgrade would also eventually provide the extra power necessary for the proposed second target station, or STS. The design of the second target station is less mature, but the project could cost in the range of $1 billion and include about 300,000 square feet of new buildings, McCorkle said. The second target station would be on the east end of the SNS campus on Chestnut Ridge at ORNL. [Read more…]
