Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.
Organizational Overview

Brookhaven National Laboratory is entering an exciting new chapter with one of the newest and most advanced synchrotron facilities in the world. National Synchrotron Light Source II (NSLS-II) enables the study of material properties and functions with nanoscale resolution and exquisite sensitivity by providing world-leading capabilities for X-ray imaging, high-resolution energy analysis and Fast dynamics studies. The superlative character and combination of capabilities are expected to have broad impact on a wide range of disciplines and scientific initiatives, including quantum materials, energy storage and conversion, life sciences, advanced materials science, physics, chemistry, and biology and more by offering extremely bright and stable photon beam.

The NSLS-II Accelerator Coordination group collaborates with the accelerator division and photon division to support and ensure the accelerator runs smoothly. Furthermore, we develop new tools to improve machine performance, such as beam stability.

Position Description

NSLS-II has an opening for a Postdoctoral Research Associates in R&D to explore new methods to improve beamline photon beam stability. Reporting to the Accelerator Coordination Group Leader, the selected candidate will join a research effort on developing, testing and implementing feedback to enhance photon beam short- and long-term stability at selected beamlines. The selected candidate will collaborate with accelerator and beamline scientists and technical staff using storage ring and beamline instruments.

Essential Duties and Responsibilities:

  • Lead the research to improve photon beam stability by combining electron and photon slow and fast feedback
  • Build the model to simulate the feedback performance
  • Setup the test platform to validate the model
  • Perform beam experiments with collaborators
  • Communicate research progress, challenges and achievements
  • Dissemination of the research results as progress reports as well as peer-reviewed publications
Position Requirements

Required Knowledge, Skills, and Abilities:

  • PhD degree in accelerator physics or related field
  • Knowledge on principles of feedback control
  • Proficiency in high level programming languages, Python and Matlab
