Repairs completed; SNS nears restart

The Spallation Neutron Source, which has been shut down since early September (initially because of the premature failure of the target vessel and then a leak in a section of the linear accelerator), is apparently nearing restart of operations and a return to research.

“Refurbishment and reassembly of the Medium Energy Beam Transport is complete,” Ron Crone, acting associate lab director for neutron sciences, said in an email response to questions.

An evaluation with a test beam to confirm proper operation of all beam handling and diagnostic systems was scheduled to begin late today (Friday), Crone said.

“All other accelerator systems have been brought on-line and are ready to support restart,” he said. “If all MEBT systems check out well and no other issues develop then startup of the accelerator and beam delivery systems will begin on Saturday, Oct. 18 with a goal of beginning beam operations to target by Sunday, October 19.”

The SNS team expects to resume neutron production for researchers early next week, Crone said.
