Description
Liquid-plasma interactions are vital to advancing applications such as plasma water treatment, nanoparticle production, and biomedicine. However, many open questions remain in understanding breakdown mechanisms in liquids, particularly the formation and evolution of plasma structures. Here, we optimized a laser betatron source for single-shot x-ray imaging of nanosecond pulsed discharges in liquids. Nanosecond time-resolved measurements enabled analysis of the size, density and evolution of plasma channels, as well as the formation of instabilities, not observable using conventional optical diagnostics. These measurements provide new insight on electrical breakdown processes in liquids, and highlight the unique capabilities of laser-driven x-rays for dynamic imaging.
