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

Figure 9

Qualitative opposite extreme deformation (top and bottom) of different vibration modes obtained by modal analysis of sample #1 SGL R6650 that coincide with dominant frequency contributions were measured during the experiment. The vibration modes have frequencies of 153.4 (a), 186.4 (b), 319.5 (c), 477.3 (d), 804.0 (e), 899.7 (f), and 978.4 kHz (g). Color coding qualitatively represents the normalized magnitude of deformation. Scale bars correspond to 10 mm.
