Figure 9

magnet geometry

Same plot as Figure 4 except that we have added a shield to contain the synchrotron radiation photons generated by the decay electrons

Here we show a cross section of the dipole with the additional shield for stopping synchrotron radiation generated by the decay electrons. The shield concept is outlined in Figure 8. Here we note that the shield used in the toy model is taken to be quite thick in order to ensure that very little energy can leak through. Given the observed minimal photon penetration of the shield we anticipate that it could be made much thinner. In future studies we intend to investigate a baffled shield configuration, with integrated channels, that could be useful for vacuum pumping.
