Time-resolved X-ray diffraction and spectroscopy under extreme conditions

June 15, 2010

Brookhaven National Laboratory, Bldg. 703, Large Conference Room

Workshop Organizers:  Vitali Prakapenka and Alexander Goncharov

Materials properties under extreme conditions are central for many fields of science. These include synthesis of new materials with improved properties, energy and defense technologies, reaction chemistry of energetic materials, and environmental and planetary sciences. In spite of numerous recent technical advances, the development of the required in situ measurements of materials properties under extreme conditions remains a challenging problem. Moreover, study of physical and chemical phenomena on very short time scales comparable to phase and electronic transitions, heat transport, atomic diffusion, and fast chemical reactions require development of novel time-resolved techniques.

To address these present and future challenges, we propose to develop and build a beamline at NSLS-II, which would specialize in temporally and spatially resolved measurements of material properties under extreme conditions of high pressure, extreme temperatures, high strain rate, and high magnetic field, created by static and dynamic mechanical and laser techniques.

At the workshop we will review new opportunities related to NSLS-II for study of materials under extremes. Based on the discussions we will determine most suitable techniques for NSLS-II and formulate the requirements for the proposed beamline. Finally, we will discuss possible technical solutions for realizing these plans, which include a conceptual design of the beamline.
