The conceptual design for a novel SSC detector that focuses on calorimetry is presented. The physics goals include searches for elementary scalars of low mass ( M H < 2 M w) and high mass ( M H > 600 GeV), for heavy supersymmetric matter, for compositeness and for strong vector-boson interactions. Examples of the relevant signatures are H → γγ; H → ZZ ∗; H → lvq q, llvv, llq q; g g → E T miss + > 2 jets ; and a jet excess at high p T . These goals may be achieved with high precision, fast, compensated and hermetic calorimetry, optimized for electrons, photons, and jets. The design allows for total hermeticity to η = 5.5 missing energy. All the goals require operation at high luminosity and the additional concerns of γ-γ and jet-jet separation, as well as survival in a high radiation environment, are addressed by an unusually large inner radius of the detector. The detector concept consists of the following few and well defined components: a scintillating fiber tracking system incorporating an imaging preradiator, a projective, finely segmented, thick scintillator calorimeter; and a muon TRD trigger and spectrometer.
