Figure 1: Schematic of the experimental setup.
From: Visualization of nanocrystal breathing modes at extreme strains
Femtosecond X-ray pulse passes through X-ray timing monitor and then diffracts from ~100-nm-thick nanocrystal powder on a Si3N4 membrane in a transmission geometry following above-bandgap femtosecond laser excitation. Snapshots of the time-resolved diffraction pattern are recorded on a large-area detector read out on a shot-by-shot basis. At right is raw diffraction image from CdS nanorods. FWHM, full-width at half-maximum.
