* Date & Time : Jan,  29 (Friday)  2:00  ~  3:00 pm

* Abstract
Recent advancements in intense, pulsed light sources provide revolutionary capabilities to subject matter to extreme conditions of pressure and temperature, creating novel conditions that span all the way from solid state to ideal plasma. Those sources also provide new powerful tools to diagnose those novel conditions. The state of matter between the solid state and ideal plasma is known as warm dense matter (WDM). There have been upsurge in interest toward WDM which cannot be predicted within presently available framework. In this talk, Thomson scattering measurements of warm dense matter will be presented [1,2].  

In second part of talk, Matter in Extreme Conditions (MEC) instrument will be introduced. The MEC instrument is being designed to provide unique access to a combination of high power optical lasers, the world first hard x-ray electron laser (FEL), and a suite of diagnostics. Extending over fields as diverse as astrophysics, fusion energy and materials science, the MEC instrument will cover a large region of high temperature and high density matter. The focus research areas include warm dense matter, equation of state, hot dense matter, and behavior of high-pressure materials.
