e[sup +]e[sup −] and ep options for the Very Large Hadron Collider
Jim Norem · AIP conference proceedings · 1998
Although the linear collider is ultimately capable of higher energies, a circular e+e− collider installed in the large tunnels of a Very Large Hadron Collider (VLHC) has attractive features, including very light magnet system and unchallenging vacuum requirements. An ep collider, built either in the 3 TeV booster or the large tunnel, could extend the HERA program beyond √s∼1 TeV. Both machines could perhaps use the same rf system, first in the booster tunnel and then as part of the large collider.
