Summary
We propose to study the photoproduction of states containing heavy quarks, charm and beauty, using a multiparticle spectrometer at the Tevatron. The apparatus is similar to that used in E87 and E401, but is upgraded to have a much larger acceptance, better ..gamma.. and ..pi../sup 0/ reconstruction capabilities, and a prompt decay vertex detector. To achieve high sensitivity to low cross sections, the experiment must run in a wide band photon beam, preferably the new beam proposed for the Proton East area. The experiment has two phases. Phase 1 is a 500 hour run with a thick target (1 interaction length) and a beam dump. This phase will produce a large sample of dimuon decays of T's and J/PSI's with energies up to 450 GeV and will measure the size of beauty photoproduction through the detection of multimuon final states. Phase 2 is a 1500 hour run with an open geometry and a 10% interaction length target. We will collect very large samples (> 10/sup 6/) of charm particle events and will search for specific B-meson and B-baryon final states. The power of the spectrometer and the flexibility of the trigger scheme we employ enables us to do sensitive searches for completely new phenomena with less bias than other experiments.
