Technical Design Report Super Fragment Separator

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.
