Supersonic Water Jets Impacting on Aluminum Targets: High Speed Images

These data were acquired during experiments at ID19 of the European Synchrotron Radiation Facility (ESRF) during the Shock BAG experimental campaign MI-1523, in which a high-voltage, high-current pulsed power driver was used to drive exploding conical wire arrays and generate supersonic water jets. The wire arrays were driven by a 95 kA electrical discharge with a current rise time of approximately 550 ns. The resulting jets were recorded during free flight and during impact on aluminum targets of different thicknesses. The data consist of multi-frame enhanced phase-contrast X-ray radiography videos of supersonic water jet free flight, impact on a thick aluminum wall, and penetration experiments through aluminum foils of different thicknesses. Six experimental configurations are included: (1) jet free flight; (2) jet impact on a thick aluminum target; (3) jet impact on a 100 μm thick aluminum target; (4) jet impact on a 200 μm thick aluminum target; (5) jet impact on a 300 μm thick aluminum target; and (6) jet impact on a 500 μm thick aluminum target. These data are organized in the folders Jet_Free_Flight, Jet_Impact_Aluminum_Wall, Jet_Perforation_Aluminum_100um, Jet_Perforation_Aluminum_200um, Jet_Perforation_Aluminum_300um, and Jet_Perforation_Aluminum_500um, respectively. For each experimental configuration, the data consist of high-speed X-ray radiography recordings acquired with two synchronized Shimadzu cameras. Recordings from the Shimadzu HPV-X2 camera are provided in the X2 subfolder and were acquired at 5 Mfps with a spatial resolution of 32 μm/pixel. Recordings from the Shimadzu HPV-X3 camera are provided in the X3 subfolder and were acquired at 5.71 Mfps with a spatial resolution of 24 μm/pixel. For each camera, the dataset includes the main experimental recording, named main_shot.tif, and a corresponding background recording, named background.tif.
