2/spl times/2 TeV /spl mu//sup +//spl mu//sup -/ collider: lattice and accelerator-detector interface study

The design for a high-luminosity /spl mu//sup +//spl mu//sup -/ superconducting storage ring is presented based on first-pass calculations. Special attention is paid to two low-/spl beta/ interaction regions (IR) whose optics are literally interlaced with the collider detectors. Various sources of backgrounds in IR are explored via realistic Monte Carlo simulations. An improved design of the collider lattice in the neighborhood of the interaction points is determined by the need to reduce significantly background levels in the detectors.
