The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory is a state-of-the-art synchrotron facility that produces high-brightness X-rays for cutting-edge scientific research. The Accelerator Physics Division at NSLS-II advances beam dynamics, RF systems, diagnostics, and accelerator technologies that enable reliable high-current operation of present and future ultra-low emittance synchrotron light sources.

Position Description

The NSLS-II Accelerator Physics Division is seeking a Postdoctoral Research Associate to conduct research on multi-harmonic RF cavity systems and advanced bunch-stretching techniques for ultra-low emittance storage rings.

What you'd do

  • Conduct analytical and computational studies of multi-harmonic RF cavity systems for bunch lengthening in ultra-low emittance storage rings.
  • Investigate beam loading effects, transient beam-loading phenomena, fill-pattern dependence, and longitudinal beam stability in active and passive harmonic cavity configurations.
  • Evaluate operating conditions and optimize RF system parameters, including cavity voltages, phases, detuning frequencies, and feedback settings, to achieve stable bunch-lengthening solutions.
  • Perform numerical simulations using accelerator physics codes such as ELEGANT and related software to study longitudinal beam dynamics and coupled-bunch instabilities.
  • Work closely with NSLS-II RF engineers and accelerator physicists to assess the feasibility of proposed multi-harmonic cavity configurations and define operational requirements for future implementation.
  • Support preparation for beam-based studies and experimental benchmarking of harmonic cavity systems at NSLS-II.
  • Present research results at scientific meetings and conferences and publish findings in peer-reviewed journals.
  • Ph.D. degree in Physics or a related discipline with research experience in accelerator physics, beam physics, or RF systems.
  • Strong background in accelerator beam dynamics, with emphasis on longitudinal beam dynamics, RF systems, beam instabilities.
  • Demonstrated experience with analytical modeling, numerical simulations, and scientific computing for accelerator physics applications.
