Synchrotron Radiation of 20 TeV protons at the design circulating current of the SSC dominates the refrigeration heat load of the 4.15 K cryogenic system. An earlier paper suggested that the synchrotron x-rays could be piped by total external reflection from polished metal surfaces to “warm” absorbers to relieve this heat load. Although the piping efficiency discussed earlier is now known to be unrealistic, it can be shown that significant power can be saved nonetheless on detailed consideration of a realistic lattice. Specifically, judiciously placed radiation absorbers could intercept much of the radiation. Four alternative schemes are discussed.
