The National Synchrotron Light Source is a state-of-the-art, medium-energy (3-billion-electron-volt, or GeV) electron storage ring that produces x-rays up to 10,000 times brighter than the NSLS. The mission of the National Synchrotron Light Source is to provide extremely bright x-rays for basic and applied research in biology and medicine, materials and chemical sciences, geosciences and environmental sciences, and nanoscience. To support this program, the NSLS-II must design, fabricate, assemble, test, install, and operate unique research equipment to generate, transport, transfer, accelerate and focus electron and X-ray beams. This includes a combination of custom designed and built parts and vendor produced components developed by a collaboration of the NSLS-II scientific, engineering, and technical staff. NSLS-II supports an international user community of over 2,200 researchers from 400 universities. NSLS-II performs all these functions in an environmentally responsible and safe manner, under a rigorous conduct of operations approach.

Position Description

NSLS-II is seeking a Postdoctoral Research Associate to participate in our research program focused on using data-driven chaos indicators for optimization of nonlinear dynamic systems and application in accelerator design and operation. The appointment will be for 2 years.

Essential Duties and Responsibilities:

• Work on a DoE funded Field Work Proposal

• Work with accelerator physics and engineering experts on online optimization of the NSLS-II accelerator complex

• Working with accelerator physics and engineering experts to create a digital twin for the NSLS-II accelerator complex

• Work with NSLS-II upgrade workgroup on the design and optimization of the NSLS-IIU lattice candidates

• Give presentations and report ongoing work

• Present technical papers at conferences and publish in peer-reviewed journals
