Sarah Mariehelen Cousineau

Section Head for Accelerator Science and Technology

Sarah Cousineau attended the graduate school at Indiana University with support of a Women in Science Fellowship, where she performed research on high intensity accelerators including the Indiana University Cooler Injector Synchrotron, the Los Alamos National Laboratory Proton Storage Ring, and the ORNL Spallation Neutron Source Accumulator ring, which was under design. After receiving her PhD in 2003, she joined Oak Ridge National Laboratory in 2003 during the commissioning of the Spallation Neutron Source accelerator.  For the next decade she participated in the commissioning and power ramp up of the accelerator complex.  In 2016 she became the Group Leader for the Beam Science and Technology group, followed by a transition to Section Head for Accelerator Science and Technology section in 2020.  From 2012 through 2020 Sarah additionally held a Joint Faculty appointment with the University of Tennessee.  Sarah is active in the accelerator community and has served as Chair for the American Physical Society Division of Physics of Beams, and is also a faculty member and the Curriculum Chair for the US Particle Accelerator School, the primary educational institution in the field of Accelerator Physics.  In 2020, Sarah was elected as a Fellow of the American Physical Society.  Her research throughout her career have included collective effects in beams including space charge and instabilities, high power beam collimation, novel beam instrumentation and diagnostics methods, charge exchange injection methods, simulation of high intensity beam dynamics, and machine learning for accelerator applications.
