Particle mass identification capability will be very important for much of the physics at ISABELLE. It will be required for studying quantum number flow in quark--quark scattering (jet and high P/sub t/ physics), hadronic decays of W's and Z's, and ''onium'' states. It will be essential for detecting and studying ''naked flavor'' states and generally required or at least very useful for most hadronic physics at ISABELLE. The large all-purpose detectors envisioned for ISABELLE require particle identification covering up to 4..pi.. solid angle with high multiplicity capability, high rate capability, insensitivity to high magnetic fields, and large dynamic range (1 to 400 GeV/c). In addition, it would be desirable to have this information for on-line event selection. At present there are only four practical methods for doing charged hadron identification: time-of-flight, dE/dX (ionization sampling), transition radiation, and Cerenkov radiation. All these methods need independent momentum determination and are effective over only limited kinematic ranges. Although the status and foreseeable development of these techniques are discussed at length elsewhere their expected capabilities are summarized in order to compare them with Cerenkov techniques. For the sake of argument a 4..pi.. steradian detector with an inner radius of 2 m is assumed.
