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

Figure 3

Energy deposition density and simulated temperature distribution. Peak energy deposition density in the transversal plane per primary 440 GeV proton for an inhomogeneous Gaussian intensity profile with σ_H = 1.46 mm and  = 1.02 mm in the tantalum cores along the length of the sample stack (a). Simulated radial temperature distribution in the horizontal plane and center of sample #6 for different times after beam impact by a single pulse of 6 × 10¹¹ protons (300 ns). The dashed line indicates the radial temperature distribution in the vertical plane directly after beam impact (b).
