The X-ray Science Division of the Advanced Photon Source (APS)  at Argonne National Laboratory (ANL) is offering an Assistant Physicist position to conduct research and development of the cavity-based x-ray free-electron lasers (CBXFELs) -- CBXFEL x-ray cavities in particular. CBXFELs are future fully coherent hard x-ray sources of utmost spectral brightness. The R&D will be performed in a framework of a collaborative project of ANL and SLAC (SLAC  National Accelerator Laboratory). The project is focused on demonstration of a test CBXFEL integrated into LCLS FEL at SLAC. 

The successful candidate will:

• Play a role in development, accomplishment, and characterization of x-ray optics and x-ray diagnostics components for the CBXFEL x-ray cavity  as well as  in deployment of these components into the test CBXFEL x-ray cavity.

• Play a role in preparation of the x-ray cavity system for the CBXFEL experiments.

• Contribute towards the  execution of the CBXFEL test experiments at LCLS.

• Contribute to the development of x-ray cavity alignment procedures – with application of machine learning tools in particular.

• Contribute to R&D activities for realization of  the real full fledged CBXFELs (beyond the test device).

• Document research results; present them at meetings and conferences; and  publish research results in the refereed journals and conference proceedings.

Position Requirements

• Bachelors + 5yrs, Masters +3yrs, PhD + 0yrs required, PhD in physics with 2+ years of postdoctoral experience preferred

• Solid knowledge in optics (x-ray optics in particular), free-electron laser physics, photon detectors, and x-ray techniques

• Strong skills in experimental physics and experience in controlling complex  systems at synchtrotron or XFEL facilities

• Competence in using complex software and ability to develop new software tools

• Ability to understand abstract physical concepts and the ability to synthesize experimental results into a proper theoretical framework

• Good written and oral communication skills for presenting new ideas, writing scientific papers, and presenting research results at scientific meetings

• Proficiency in  Linux operating system, EPICS-based controls environment, Matlab, Python and other programming languages,  LaTeX document preparation system, and advanced graphical tools

• Role model Argonne’s Core Values

• Understand, value, and promote diversity
