Job Description

The Compact X-ray Free-Electron Laser (CXFEL) laboratory at Arizona State University (ASU) invites applications for a full-time position as a X-ray Instrument scientist with specific skills and experience in commissioning and operation of precision UHV instrumentation. The CXFEL facility comprises 15,000 sq. ft. of state-of-the-art laboratory space in the new Biodesign C building at the Tempe campus.  ASU has embarked on a multi-phase project to develop ultrafast x-ray beams, beginning with the compact x-ray light source (CXLS) that is now under construction. CXLS uses a compact electron accelerator and high-power lasers to produce x-rays via inverse Compton scattering (ICS), resulting in sub-ps pulses at up to 1000 Hz. Resulting scattering patterns will be collected at full rate with a 4M Eiger2 X to enable so called single shot experiments. For time resolved experiments a flexible fs laser will become part of the instrument. The precision electronics for the accelerator and instrument will be controlled by a single EPICS system. Most of the experiments will be performed in a complete UHV system. Additionally, a humidified sample environment is foreseen.  Several activities require adherence to clean-room protocols, laser radiation safety protocols, ionizing radiation safety protocols. When complete, CXLS will be employed for time-resolved studies of atomic and molecular processes, quantum materials, chemical dynamics, and biological phenomena. Assembly and engineering testing of CXLS accelerator and experimental hutch systems will begin in summer of 2019 with commissioning activities beginning January 2020. The Instrument Scientist in this position will be an important member of an integrated team of physicists, engineers with the task of building a user facility to serve scientists from a spectrum of disciplines inclusive of protein crystallography; soft matter physics; materials science; atomic, molecular, and optical physics; and quantum materials.

Essential Duties

  • Participate in the design of experimental end stations with project engineering and with oversight and guidance of the lead Project X-ray Instrument Scientist.
  • Participate in the building and testing of end stations with duties that may extend from specification to procurement, to quality control receiving, to precision assembly of integrated UHV test chambers and humidified He gas environmental chambers.  
  • Participate in the building and testing of the CXLS instrument as determined by project priorities and development timelines. Duties may extend to assisting in the build and test of accelerator systems, laser systems, vacuum systems, and control systems. 


Minimum Qualifications

Bachelor’s degree in Engineering or related field AND five years of engineering or related experience; OR, nine years of engineering or related experience; OR, any equivalent combination of experience and/or education from which comparable knowledge, skills and abilities have been achieved.


Desired Qualifications

  • Evidence of a Ph.D. in X-ray science instrumentation development that involved X-ray diffraction or X?ray imaging
  • Experience with pump-probe and time resolved kinetics (of mixing) experiments.
  • Experience with X-ray and optical spectrometry.
  • Working knowledge of experimental control and data acquisition systems. Experience with Experimental Physics and Industrial Controls System (EPICS) software is desirable.
  • Experience with X-ray diagnostics and precision assembly of X-ray instrumentation.
  • Data analysis experience of X-ray experimental datasets.
  • Experience with Python script programming.
  • Experience working at a X-ray beamline (synchrotron or XFEL) or in a similar national user facility.
  • Experience collecting and refining X-ray structural data. (3 years)
  • Experience commissioning of advanced instrumentation and detectors.
  • Demonstrated knowledge of EPICS.
  • Demonstrated working knowledge of data acquisition and control systems, and signals and systems.
  • Demonstrated working knowledge working with vacuum, HV, and UHV systems from part cleaning to clean assembly, to bake-out with pump-down, to routine operations with experimental chambers.


Working Environment

  • Regular activities require ability to manage multiple tasks at one time, to be able to prioritize tasks; to manage conflict; to interact in a team environment; and to communicate through verbal and written work.
  • Activities are performed in an environmentally controlled office setting and laboratory subject to extended periods of sitting, keyboarding and manipulating a computer mouse; required to stand for varying lengths of time and walk moderate distances to perform work.
  • Frequent bending, reaching, lifting, pushing and pulling up to 25 pounds.
  • Regular activities require ability to quickly change priorities, which may include and/or are subject to resolution of conflicts.
  • Ability to clearly communicate verbally, read, write, see and hear to perform essential functions.
  • May be required to wear personal protective equipment before entering laboratories such as lab coat, gloves, safety glasses, closed toe shoes, and respirator.
