Report of the intermediate-)ital p)/sub perpendicular/ detector group: A beauty spectrometer for the SSC (superconducting super collider)

Abstract

A ''Beauty Spectrometer'' has been designed for studies of B physics at the SSC. The ultimate goal is a definitive measurement of CP violation in the B system. The spectrometer consists of two stages and occupies one side of an intermediate-luminosity interaction region. An upstream, or intermediate, stage extends from the interaction point to 14 m and covers the angular region from 57 mrad (3.3 degree) to 350 mrad (20 degree). The forward stage extends to 77 m and to angles down to 5.7 mrad. The design includes silicon microstrip detectors, conventional tracking, momentum analysis, and hadron and lepton identification. While no fundamental problems have been found, the detector must deal with unprecedented particles fluxes, trigger rates, and data rates. 11 refs., 10 figs., 5 tabs
