In shock-wave experiments, high-powered lasers or guns are used to send a supersonic pressure wave through a sample. This type of dynamic compression can generate immense pressure and allows for the study of impact phenomena in real time. These experiments have wide applications for Earth and planetary science, ranging from understanding the effects of meteorite impacts to studying the structure of planetary interiors. Dynamic experiments are short-lived, generally having a duration of tens of billionths of a second. This requires the development of ultrafast experiments. In this talk, Tracy will review new results using high-intensity pulsed x-rays to examine the crystal structure of shock-compressed minerals.
