DRAFT Figure 2.4.167: Deposited energy per primary uranium ion at the entrance of the first (left) and second (right) quadrupole magnet behind the 4 g/cm2 carbon target. The maximal energy density deposited by one spill in a part of the coil of the first quadrupole magnet is 0.0256 MeV/cm 3 per incident ion or 0.46 mJ/g for 10 12 ions. The calculation was performed for the case of a 1500 MeV/u uranium beam impinging on a 4 g/cm 2 target. This value is below the quench limit but the total power deposited exceeds the practical limit for a cryo system. Hexapole behind the beam catcher at PF1: At the beam catcher positions at BC1, BC2 and PF1 the full primary beam can be dumped. Much thicker shielding is therefore required than in the target area. The simulation using PHITS showed that 80 cm of iron is suited to suppress the neutron flux sufficiently. The geometry investigated is shown in Figure 2.4.168. Here, the graphite part had an inclined surface to increase the range straggling and thus the energy-loss density in the bulk material is substantially reduced. Critical for the exposure are the coils of the following hexapole magnet. Figure 2.4.168: Geometry of the beam catcher in front of the hexapole magnet at PF1 used in the PHITS calculation [41]. 214
DRAFT In a side view the flux of protons and neutrons is shown in Figure 2.4.169 and Figure 2.4.170. Whereas the uranium ions are stopped in the graphite, an intense beam of protons deeply penetrates into the iron. Outside of the beam catcher the radiation is dominated by neutrons scattered in a wide distribution onto the hexapole magnet. Figure 2.4.169: Fluence of protons per incident 238 U ion at 1500 MeV/u in the beam catcher area at PF1. Figure 2.4.170: Fluence of neutrons per incident 238 U ion at 1500 MeV/u in the beam catcher area at PF1. The maximum deposited energy density in the coil in the direction of the incident primary beam of 0.045 MeV/cm 3 corresponds to 0.81 mJ/g for 10 12 uranium ions.
