Arizona State University: Office of the Executive Vice President Knowledge Enterprise: Biodesign Institute: Biodesign Beus CXFEL Lab


Tempe, AZ

Open Date

May 30, 2024


Arizona State University has embarked on a multi-year project to develop novel compact X-ray sources including the Compact X-ray FEL (CXFEL) generating ultrashort and coherent X-rays in a room-sized facility. The scope of the project includes both the construction of the x-ray light source and construction of endstation focusing on biology, AMO physics, and condensed matter physics. We invite applications for a Postdoctoral Research Associate working on the application of ultrashort x-rays to current scientific applications in condensed matter physics. The successful applicant will join the team constructing the Compact X-ray Free-Electron Laser (CXFEL) under a recent NSF midscale research infrastructure award. CXFEL will be a novel fully coherent x-ray laser capable of temporal and spectral shaping of the x-ray output down to attosecond timescales that presents opportunities to develop an original research program in ultrafast science of quantum materials. The successful candidate will participate in construction and commissioning of the CXFEL quantum materials endstation, participate in commissioning experiments at ASU’s existing Compact X-ray Light Source (CXLS), and XFEL beamtimes as appropriate to build expertise in the operation and construction of XFEL experiments.

Essential Duties

The postdoc is also expected to participate in the commissioning and early science experiments on the instrument. The postdoc is expected to take a leadership role in the design and construction of the equipment related to Quantum Materials research at CXFEL. This includes construction of femtosecond laser diagnostics and long-wavelength generation setups, controls and monitors for x-ray detectors, construction and characterization of vacuum chambers, commissioning of closed cycle cryogenic systems and load locks. This position also includes the opportunity to participate in and lead beamtimes at the ASU CXLS, XFEL and synchrotron user facilities to inform the design and construction of the CXFEL quantum materials endstation.

The postdoc is expected to train and supervise graduate and undergraduate students, be highly skilled in technical writing including lab reports, scientific presentations and publications. The postdoc is expected to work in multidisciplinary teams that span different research areas and academic units.
