The SLC as a second generation linear collider

With enough luminosity, the SLC could contribute to most of the high energy physics of current interest such as new hadrons, quark molecules, glueballs and studies of the standard model and minimal supersymmetric SM in the form of particle searches for the lowest mass Higgs or selectron or tests of the point-like predictions for the W, Z or e˜_R. Some experiments require alternative incident channels such as eγ and γγ but only modest increases in energy. Just as the SLC was a prototype for the NLC, it could also be a prototype for a general (or gamma) linear collider-a GLC. Because the main problem is luminosity, we give a scaling relation based on multiple bunches per RF pulse. We then ask what is possible for the SLC in terms of bunch and train current, emittance and energy at the IP. The results suggest a phased development with the Higgs as a possible last step requiring a luminosity L⩾10³²
