Simulations of SNS Target

Simulations of SNS Target


  • Charlotte Barbier, Neutron Technologies Division
January 17, 2018 - 10:00am to 11:00am


A liquid mercury target is used at Oak Ridge National Laboratory’s  Spallation Neutron Source (SNS) to generate neutrons. The mercury is flowing in a stainless steel containment vessel for neutron spallation, but also to cool the vessel itself. When the proton beam hits the target (1.4 MW at 60 Hz), the rapid rise in temperature causes an intense pressure wave that propagates in the mercury and into the vessel wall. In this presentation, the engineering workflow for the SNS target will be presented: mesh and simulation time requirements for the structural and fluid analysis will be explained in details.


Charlotte Barbier is a Mechanical Engineering Researcher in the Spallation Neutron Source Division at Oak Ridge National Laboratory. Her expertise is in the field of Fluid Mechanics and heat transfer, with experience in computational fluid dynamics and in experimental fluid mechanics. Dr. Barbier has worked on a variety of fields/industries, including: Hard Disk Drives, Biology, Bio-Inspired sensors, Naval Research, ITER, Climate change, and SNS. She has a M.S. in Mechanical Engineering from Centrale Lille, France, and a PhD in Mechanical and Aerospace Engineering from the University of Virginia.
