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

Figure 5

Radial surface velocity of target #1 R6650 after impact with 1 × 10¹¹ ppp (25 ns pulse length) as recorded by the LDV. Dynamic response within the first 25 μs after beam impact (a). Response between 150 and 180 μs after beam impact (b). Full response of the target. The dashed red lines represent a guide to the eye for the damping envelope (c).
