Objectif
Joint high-pressure research in the regime 10-100 Mbar is planned, based on new laser compression techniques. This project, concerns the structure of highly compressed matter, in particular insulator-metal transitions, and applies to astrophysics, big planets, and inertial fusion. It goes beyond dynamical detonation methods limited to pressures of about 10 Mbar.
The experimental group at MPQ recently demonstrated the generation of plane shock waves above 10 Mbar using X-ray driven ablation in laser-heated cavities, and pressures up to 100 Mbar and beyond are within reach using flyer plates. This method represents a break-through towards quantitative measurements at ultra-high pressures in the laboratory. The challenge consists in using tiny probes of matter, some mg in mass and 10-100 mm in size, and fast (picosecond) diagnostics. Further development of the technique requires extensive theoretical and numerical support to control and hydrodynamics, including radiative transfer, and for identifying in detail the most promising experimental configurations.
Structured targets and multiple shock dynamics will be studied with the aim of achieving low entropy compression and access to the interesting regions of predicted phase transitions, like the metalization of hydrogen and noble gases.
