Dream beam postdoc

DOE x‐ray light sources facilities including the Advanced Photon Source, the LINAC Coherent Light Source and the Advanced Light Source are undergoing major upgrades to increase the source brightness and enable groundbreaking science, based on laser‐like high coherent flux. The Diffraction‐limited Radiation Enhancement with Adaptive Mirrors (DREAM) project (dreambeam.lbl.gov) takes advantage of recent technological developments in the field of x‐ray adaptive optics to shape and control coherent x‐ray wavefronts at the nanometer level, tuning their properties in novel ways. The physics postdoc will work on the development of instrument controls for x-ray adaptive optics and automated beamline alignment. They will implement wavefront sensing data analysis in EPICS instrument controls and integrate it with the bluesky user interface (https://nsls-ii.github.io/bluesky/) to allow synchrotron users measure and potentially shape the wavefront to enable a new class of coherent x-ray experiments. They will develop machine learning solutions for optical systems, in collaboration with other DOE light source facilities (APS, NSLS-II, LCLS-II) and evaluate the performance at a pilot beamline.

About the ALS:

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. 

The core values of the ALS reflect a strong commitment to diversity, equity, and inclusion.  We seek candidates who support a culture in which each member of the ALS community feels welcomed and valued. An ongoing commitment to recruiting a vibrant, diverse and talented workforce is paramount to promoting a diverse lab community.
