This satellite workshop is dedicated to exploring the science cases and instrumentation for Extreme Conditions research using high pressure devices such as Diamond Anvil Cells (DAC) and Large Volume Presses (LVP) at PETRA IV. Scientific case studies will benefit from 1) the exceptional brightness and coherence from very small gap undulators with a maximum length of 10 m (signature beamlines) delivering high energy flux, enabling focused micro- to nano-sized beams on the sample, as well as 2) offering the chance to use an entire suite of coherent diffraction and imaging techniques that have so far not been possible at high energies. We will summarize and critical discuss the 5 key areas proposed in Scientific Instrumentation Proposals (SIP)drafts, offering the community the chance to view, comment and provide feedback before the submission deadline (1st December 2020):
- LVP Instruments (diffraction/imaging in the 6-ram LVP & dedicated imaging/diffraction in a PE-type press)
- High-P, high-T DAC X-ray diffraction and imaging microscope
- A high pressure PETRA IV endstation combining Spectroscopy and Diffraction
- A dynamic Compression X-ray Diffraction/Imaging Microscope
- Non-resonant Inelastic X-ray Scattering (NIXS) and Nuclear Resonance Scattering (NMR) in a DAC
Topics of discussion will be considered within the framework of the CDR chapters on Earth and Environment and Materials for Energy and Transport Technology. Discussions include high-pressure investigation of materials structure, physical properties and kinetics of transformational processes using X-ray diffraction, spectroscopy and imaging techniques. Particular consideration will be given to the emergence of new and advanced techniques, such as time-resolved microtomography, phase contrast, coherent Bragg diffraction imaging, ptychography, and synchrotron Mössbauer spectroscopy. Technological advances in high pressure generation in conjunction of with PETRA IV, processes the driving forces leading to novel phase discoveries and the study of complex geological materials to explore a wider (towards smaller) length and time scales than currently possible.
After the workshops, the SIPs will be finalized for submission with the aim to support new, dedicated, instruments for Extreme Conditions Research at PETRA IV in order to meet upcoming challenges and demand by the community in this rapidly growing field of research.
The workshop will be virtual and presented through ZOOM.
