Abstract Scope When shocked, materials can produce a spray of small ejecta particles ahead of the free surface. Richtmyer-Meshkov Instability growth of surface defects, such as machining marks, has been identified as a principal cause of ejecta. In this work, we identify another potential mechanism for ejecta production with computational and experimental studies. Here, if cavitation due to a first-shock release results in near-surface cavitation bubbles, a subsequent shock can collapse these bubbles resulting in substantially larger quantities of ejecta than RMI mechanism with temperatures well over 2000 K. This work covers sensitivities in experiment and computation on this phenomenon, in particular the impacts of shock history and previous RMI ejecta sourcing.
