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

Figure 10

Continuous wavelet transformation of the radial surface velocity obtained in the experiment and by simulation for sample #1 SGL R6650. The normalized power spectral density plot is overlaid in light grey. Solid white lines indicate vibration modes of the target geometry obtained by modal analysis. Experimental result at 1 × 10¹¹ ppp (a), 6 × 10¹¹ ppp (b), and simulation result at 1 × 10¹¹ ppp (c).
