Summary of the working group on large magnetic spectrometers. Part II. Large magnetic spectrometer tracking as much of 4 - as practical

Proposed is a large magnetic spectrometer to track and momentum analyze a very large fraction of the particles emitted in a heavy ion collision. This will allow us to determine pseudorapidities (and rapidities when particles are identified), to reconstruct neutral Vee's and have momentum information on both positive and negative particles in the same vent. We plan to handle gold on gold events at 100 GeV/nucleon in RHIC. Particle identification can be made kinematically under certain conditions for K0, lambda, Σ, Xi, Omega- and their anti-particles as was done historically in bubble chambers and more recently in electronic detector spectrometers like the MPS and others, etc. The negative particles will be predominantly pions. In addition, highly segmented Cerenkov hodoscopes, as well as time-of-flight and dE/dx information can be used to identify some of the particles
