Dynamic Radiation Effects Induced by Short-Pulsed GeV U-Ion Beams in Graphite and h-BN Targets

Figure 4

ANSYS-simulated time-dependent temperature evolution of a 0.5 mm-thick isotropic graphite disc for 1 ms after the impact of a 100 μs-long U-ion pulse. Coordinates can be seen in Figure 3, with all points being at x = 0. (a) Pristine material. (b) Thermal conductivity reduced to 4 W/m·K in the material of the beam spot representing graphite after 1.14 GeV U-ion irradiation to a fluence of 3 × 10¹³ ions/cm² [26].
