Washington State University (WSU) is seeking to hire strongly self-motivated, talented experimentalists to work with scientists and engineers at a first-of-a-kind experimental user facility: The Dynamic Compression Sector (DCS) at the Advanced Photon Source (APS), Argonne National Laboratory. The DCS constitutes a new paradigm for understanding the dynamic compression and deformation response of materials subjected to extreme conditions on short time-scales. Real-time, atomistic-scale investigations of condensed matter phenomena are undertaken in single event experiments through time-resolved, in-situ measurements utilizing the tunable, high energy X-ray capabilities at the APS.
We are looking to hire two experimentalists (Laser Physicist/Engineer and Optical Physicist/ Engineer) who enjoy hands-on work and problem solving in a fast-paced, research environment. The location for these WSU positions is the Advanced Photon Source, Argonne National Laboratory, Argonne, IL. The DCS research activities involve state-of-the-art, dynamic compression experiments that utilize x-ray and optical measurements on nanosecond time-scales to understand the response of materials at high dynamic stresses.
The Laser-Shock capabilities at the DCS include a state-of-the-art 100J laser and custom built target chamber system to perform well-characterized, dynamic compression experiments involving x-ray and optical measurements. The optimal performance of the laser system is a key element of the DCS research objectives. The flexibility of laser-driven dynamic compression experiments will present unique and exciting challenges and opportunities. The Laser Physicist/Engineer will participate in the operation of the 100-Joule laser for laser-shock research activities, contribute to the design and conduct of laser-shock experiments, and work with scientific users. Working with other laser experts, the individual hired will quantify and archive the laser performance for each experiment, and document and maintain safe operating procedures related to the laser and its control areas at the DCS.
2.) Optical Physicist/Engineer
The Optical Physicist/Engineer will take the lead in the design, development, and use of optical equipment and systems, for laser-interferometry measurements and other laser-based diagnostics. Many of the experiments performed at the DCS utilize a wide variety of lasers that are integral to the measurement of the shocked state of materials (e.g. pulsed high energy DPSS lasers, CW DPSS frequency doubled lasers, pulsed and CW high power IR and visible fiber lasers, short pulse low energy lasers, and pulsed and CW laser diodes). A wide array of optical detection and analysis apparatus are also utilized, including biased and amplified photodiodes, APD’s, image intensifiers, fast framing cameras, ICCD’s, streak cameras, and other state-of-the-art electro-optic instrumentation. The successful candidate, after appropriate training, will be expected to operate and maintain these systems, as well as design new systems, and select appropriate components to advance the capabilities of the DCS.
About Dynamic Compression Sector at the Advanced Photon Source, Argonne, IL
THE INSTITUTE FOR SHOCK PHYSICS
A multidisciplinary research organization within the College of Arts and Sciences, the ISP undertakes a broad range of fundamental scientific activities related to understanding condensed matter response under dynamic and static compression. Washington State University has a long and distinguished history of conducting research in dynamic compression science. In 1997, the Institute was established with support from the DOE (Defense Programs) to ensure a strong, long-term academic base for the DOE’s national security mission, and is currently funded through NNSA’s Stockpile Stewardship Academic Alliance (SSAA) program.
Continuum-to-Atomic level understanding is the pervading scientific theme of the research activities that emphasize integration of innovative experiments with theoretical and computational advances. Multidisciplinary efforts that combine expertise in Physics, Materials Science, Chemistry, and Mechanical Engineering are underway to address several exciting and challenging scientific problems. In addition to the faculty within the Institute, students and faculty from several departments within the College of Arts and Sciences and... the College Engineering participate in the Institute’s research projects. Excellent research interactions are in place with the NNSA National Laboratories: Lawrence Livermore, Los Alamos, and Sandia.
A brief summary of the Institute’s activities follows. Experimental work, under dynamic compression, typically involves fast, time-resolved measurements in single event, impact experiments. Research projects currently underway include: time-resolved x-ray diffraction studies; pressure induced structural phase transitions; understanding of inelastic deformation and failure under dynamic loading; effect of material microstructure on dynamic deformation; chemical decomposition in energetic materials; development of fast optical methods to probe shock induced changes; effect of deformation on semiconductor properties; high pressure equation of state studies; and chemical and physical changes under static high pressures. Since Professor C. S. Yoo’s appointment in 2007, a strong static high pressure research program has complemented the shock wave effort. Very recently (Summer 2013), Professor Christian Mailhiot was hired to build a strong theoretical/computational research effort to complement the experimental activities.
State-of-the-art experimental and computational facilities are housed in the Shock Physics Building. Inaugurated in 2003, the building was designed specifically for shock wave research and represents a unique facility among academic institutions. The major experimental research facilities available for studying physical and chemical phenomena over a large range of length and time scales include the Impact Laboratory, Laser Shock Laboratory, Static High Pressure Laboratory, and the Compact Pulsed Power Facility. Among the Institute’s research capabilities is a Computational Facility designed to complement the experimental effort. Further details may be seen at www.shock.wsu.edu.
