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

Figure 12

Frequency analysis of the radial surface velocity presented in Figure 8. The normalized power density within the first 100 μs after beam impact is shown for beam impacts with intensities of 1 and 6 × 10¹¹ ppp of samples #1 SGL R6650 (a), #6 SGL R6650 (b), and #3 POCO ZEE (c).
