ACHTUNG! Indico Wartung mit Dienstunterbrechung am Donnerstag dem 16.12.2021 von 10:00 Uhr - 11:00 Uhr (CET). Bitte beenden Sie ihre Arbeit rechtzeitig um Datenverlusten vorzubeugen! ATTENTION! Indico Maintenance with downtime on Thu 16 Dec 2021, 10 - 11h CET. Please finish your work in time to prevent data loss!
In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Ultrafast X-ray Studies on the Dynamics of Transitions in Geophysical Materials

Room. E1.173 (European XFEL, main building)

Understanding the processes which dictate physical properties in condensed matter, such as strength, elasticity, plasticity, and the kinetics of phase transformation/crystallization, requires studies at the relevant length-scales (e.g., interatomic spacing and grain size) and time-scales (e.g., phonon period). Experiments performed at the Matter in Extreme Conditions end-station at the Linac Coherent Light Source, SLAC combine a laser-driven dynamic compression pump and X-ray free electron laser (XFEL) probe. We present time-resolved structural and/or electronic transformations in a suite of geophysical materials. SiO2 (quartz/fused silica), a major component of the Earth’s crust, is seen to undergo a rapid transformation (within 2 nanoseconds) to a high-pressure polymorph (stishovite) on shock compression and reversion to an amorphous state on shock release. Divorcing the onset of an electronic vs. structural transition in materials at extreme conditions is now possible with single-shot X-ray emission spectroscopy as evidenced by simultaneous electronic spin-transition and structural phase transition data collected on a Fe-bearing silicate, bridgemanite. This mineral, composing 40% of the Earth’s mantle. Deformation mechanism and strength models of iron at near inner core conditions have significant implications for planetary evolution over a pressure range of a few to hundreds of GPa. Taking advantage of the brilliance and coherence of XFEL technology coupled with a dynamic driver provides an experimental platform that takes us to the frontier in condensed matter physics.
