Dynamic Response of Graphitic Targets with Tantalum Cores Impacted by Pulsed 440-GeV Proton Beams

Figure 17

Radial surface velocity for maximum applied beam intensity on sample #1 R6650 (a), #6 R6650 (b), and #3 POCO ZEE (c). Left: recorded surface velocity (solid blue line) and calculated damping envelope (red dashed line). Right: continuous wavelet transformation as a function of time up to 100 μs after beam impact.
