Instrumentation Postdoctoral Researcher

Lawrence Berkeley National Lab’s (LBNL) Advanced Light Source (ALS) Division has an opening for an Instrumentation postdoctoral researcher to work on direct write optical lithography applied to diffraction gratings. The aim is to produce a machine capable of writing straight lines into a thick silicon substrate with a period of 0.5 – 10 microns over a length of up to 300 mm with less than 5 nm placement error.  The silicon gratings are to be applied to the area of ultra-high resolution soft x-ray spectroscopy. 

The ALS is a U.S. Department of Energy (DOE) Office of Science national scientific user facility whose excellent scientific reputation, expert staff, and capabilities in the soft x-ray, hard x-ray, and infrared regimes attract more than 2,000 academic and industrial users each year in disciplines spanning physical, chemical, materials, biological, energy, and Earth sciences. It is one of five Berkeley Lab user facilities that serve a combined 14,000 users annually. The co-location of these user facilities – including the Molecular Foundry Nanoscale Science Research Center and the NERSC scientific computing center, as well as Berkeley Lab's outstanding programs in materials and chemical sciences, among others – offers a prime environment for collaborative science. The ALS has been a global leader in soft x-ray science for more than two decades and is currently undergoing a large-scale upgrade (ALS-U) that will endow the facility with state-of-the-art x-ray capabilities. It's an exciting time to join our growing team!
What You Will Do:
  • Design and build opto-mechanical mechatronic systems to enable the writing of gratings with sub 10 nm accuracy.
  • Create methods to make linear focusing elements (zone plates) for high resolution optical lithography.
  • Develop methods to tests the accuracy of gratings that are generated
  • Document and communicate the results of work in papers that are published in the peer-reviewed scientific literature.  Internal reports need to be produced to document the advances made in experimental and theoretical work.  
  • Give oral presentations, including participation in meetings, reviews, and conferences. 
  • Comply with Laboratory, Division, and Program Conduct of Operations and Quality Assurance policies and procedures for all job assignments and activities.
What is Required:
  • PhD degree in the Physical Sciences, Engineering or related discipline, 
  • Strong background in the development of complex opto-mechanical systems
  • Experience with Mechatronics
  • Strong knowledge and experience working with and building lab instrumentation
  • Ability to work collaboratively with a diverse team of scientists and engineers
  • Demonstrated record of scientific excellence through publications, talks, or software deliverables.
  • Experience contributing to a project in a team environment
  • Excellent oral and written communication skills
Desired Qualifications:
  • Experience in ultra-precision mechanical systems or the instrumentation involved in direct write optical lithography.
  • Experience in distance measuring interferometry and control systems
For full consideration, please apply by November 11, 2022. This position will remain open until filled.
